>>> GOOD NEWS, BAD NEWS <<<
"""""""""""""""""""""""""""
I hate Pain, but I hate Giving Up even more. Not a motto or a
catchphrase, but a philosophy on life. I wrote it on my mirror, so I see
it every morning when I'm shaving. I repeat it to myself when I'm working
my injured shoulder in physical therapy. I chant it in my head when I'm
bicycling up some steep hill and cursing the extra weight I've become
saddled with as I've aged.
I say it to myself as I run the morning's CoPilot pass through Genie's
A2 RoundTable.
Ever since Uncle DOS himself, Tom Weishaar of the dear, departed,
_Open-Apple_, took the reins of the Apple II areas on the Genie (then
GEnie) online service, Genie's A2 and A2Pro have been _the_ place to be
online for Apple II support. Even the coming of the Internet could not
slow down the dedicated staff and users of the A2 RoundTables.
But Genie itself could.
While General Electric was never the benevolent parent that would have
allowed GEnie to compete with the big boys of the online service world, the
service was small, but thriving, and alive with activity. In fact, much of
its charm was the fact that it was small and unique and different from the
huge online services it competed with. Just as using an Apple II is
esoteric now, using GEnie was esoteric then, and there is a certain appeal
in that.
Then General Electric sold GEnie, and it became Genie. The new owners
also chose to make it the most expensive online service in the world. Many
chose to leave, many stayed, and few new users arrived. Over time, many
more left than stayed.
The A2 faithful did not take the situation lightly. After all, Apple
II users are survivors if nothing else, and survivors find what they need
to survive. A new home for the A2 faithful was sought--one that would work
faster, be cheaper, and more accessible to the world--and eventually found:
Delphi.
Over time, Delphi A2 started catching up to Genie A2, both in terms of
quality and quantity of content. In early August, Delphi A2, potentially
_the_ hotspot for Apple II activity, got so warm it exploded with activity.
The combination of the availability of two offline readers for the Apple
IIgs, KansasFest 1997, and free Delphi access via the World Wide Web made
for leaps and bounds of growth.
At the same time, Genie's management management made it clear that
they're planning big changes for the online service. In fact, they also
made it clear that these changes were coming September 1st (see last
month's _GenieLamp A2_ for details). Unfortunately, they never made it
clear just what these changes would be (although it was clear that all
offline readers, which the production of _GenieLamp A2_ is dependent on,
would break and break spectacularly). Fortunately (or not, depending on
your perspective), these changes have still not happened.
The combination of Genie's announcements and Delphi's growth have led
to even more Genie A2 faithful moving to a new home on Delphi, and with
them has gone much of the activity of the A2 RoundTable on Genie.
Seeing what's happened on Genie, my first-ever online service, has
been quite Painful. Many friends I've known for years have left. New
friends wandering in are rare. I've thought about Giving Up, more than I'd
like to admit.
I've made a decision. The October 1997 issue of _GenieLamp A2_ will
be the last. It's a difficult decision, and it feels like Giving Up, but
the Pain of seeing what's happened to Genie the last year and a half has
been too much.
But this is not Giving Up. What will be done to fill the void caused
by the end of the 'Lamp will be to start a similar publication on Delphi.
Check the II Scribe Forum on Delphi for further information.
I'm not Giving Up because of the Pain; I'm moving on so I can still
see the light.
Finally, a quick word about the future: KansasFest 1998 is scheduled
for July 22-26 1998 at Avila College in Kansas City, Missouri.
Just because it wouldn't be a _GenieLamp A2_ editorial without a KFest
Blatant Plug.

<<<<< This is the latest answer from FEEDBACK regarding the new Genie:
"""""
Dear Mr. Huth,
I receved the following note from Genie Managemet. No dates for
implementation has been set.
You will still be able to access Genie, much as you do now. We are
expanding the services capabilites, but are not cutting back on any access
methods. We are keeping the service as similar as possible to what it
currently is so as to not present too great a culture shock as we move to
the new servers. We will make the move in such as way as make everything
as easy as possible for you the user.
We don't do this every day, so a lot of things are very fluid from the
design and implementation viewpoints.
We are working on a general update letter to be sent soon, please look for
it.

>>>>> The upcoming Genie change is on a vastly greater scale than
""""" previous changes to the Genie interface. I am not optimistic that
the Genie offline readers will be fixable after the changevoer. Hopefully I
am wrong, but it would be prudent for everyone to start hedging their bets
right now in case the OLR's prove to be difficult or impossible to fix.
With regard to joining Delphi:
The Apple II community there is growing slowly but visibly. With this
change in Genie, it may see a major growth spurt in the near future. My gut
feeling is that, because of the library and OLR situations, six months from
now the current roles and relative ranking of Delphi and Genie will be
reversed.
Right now the Delphi library only has a few hundred files in it, but plans
are afoot to automate a large-scale upload to make it into something to be
proud of like we have here on Genie. Failing that, if A2-Delphi did
something as simple as organize a hundred users into uploading a few of
their favorite files, things could start hopping overnight.
At this time file transfers on Delphi are reliable only if using Delphi's
direct-access membership option. Their "content" membership option gives
you access via your own internet dial-up through a telnet connection. To
say that file transfers via telnet are unreliable vastly understates the
case.
Having said that, There Are Rumors that Delphi has something in the works
to greatly improve file transfer capabilities, but I have no word on what
that might be or when it will surface.
In no way am I suggesting that people quit Genie and join Delphi. I myself
will be here on Genie until the bitter end, whenever that might be. But
Genie is becoming a terribly frayed basket to be keeping all of your eggs
in.

However, my little experiment indicates to me that it is possible to get

DELPHI NOW AND DELPHI FUTURE
""""""""""""""""""""""""""""
Delphi's A2 Forum is currently exploding with activity.
In the past three days alone, there have been more than 200 new messages
posted in the A2 forum. In July, A2 jumped to the 30th position in the
rankings of top 100 most active forums. If the traffic level stays
anywhere near what it has been this past week for the rest of this month,
it is quite possible that A2 will be very near the top of the heap.
If anyone hasn't checked out Delphi's A2 forum recently, I recommend it.
Although I'm sorry to see Genie struggling, and the A2 RT here vulnerable
to collapse when the new Genie takes root, I'm not a bit pessimistic.
Delphi's A2 Forum is growing by leaps and bounds, and promises to be a
wonderful on-line home for the future.

I said simple, and I do mean that. At this time, the emphasis is on
getting online, going to specific forums, posting messages, reading them,
posting email and reading it. In the beginning, a lot of configuration

HP DESKJET BLATANT PLUG I'm looking to upgrade from my ImageWriter II.
""""""""""""""""""""""" From past inquiries to this BB, I've been told
the HP Deskjet 300 is a good investment. My Apple dealer suggested the
Epson 500. I have Apple II, IBM, and Mac hardware, and a shared printer
would do me a great service. The Epson has both serial and parallel
interfaces, so I could have two computers attached at once, as well as not
needing a converter card for the Apple II.
Can anyone recommend to me one over the other? Most, if not all, of my
printing is Appleworks-related; do I want a laser or inkjet printer? What
is the difference, exactly?
-Ken
(KEN.GAGNE, CAT12, TOP13, MSG:9/M645;1)
>>>>> If you have any intention whatsoever of printing from an Apple II
""""" to this Epson printer without getting a parallel card, forget about
it.
I just checked out the specs on it and it's not an RS 232 compatible
serial, but an RS-422 compatible serial, and high speed only. This means
that it might work via the 57600 printer port driver, but your chances of
getting it to work via the serial port in Prodos 8 are between slim and
none, and Slim just got on a bus out of town. There are also no GS/OS
printer drivers available for it, so printing from the GS desktop is also a
no-go, even if you get a parallel card.
I have a Deskjet 310 (older model, been out of production for some time,
did a review of it for the final ::sigh:: edition of GS+, pretty similar to
the 300), and it works decently with a IIgs. However, to get it to work
with a Mac, you'd need to get PowerPrint.
> Can anyone recommend to me one over the other?
How about a third recommendation: get a Deskjet 340 with Macintosh
adapter, a parallel card for your IIgs, and an ABCD auto switching parallel
switchbox. This would let you print from MSDOS, OS/2, Windows 3.1X,
Windows NT, Windows 95, ProDOS 8, GS/OS, and the MacOS without changing a
single cable or flipping a single switch :)

Laser printers are faster, print at higher qualities, and have more
expensive initial costs. However, they don't do color. Inkjets have
chaper startup costs, very good quality printers, and more expensive
continuing costs (i.e. per page, ink for the inkjets cost more than toner
for the lasers). They're both pretty good.
Ryan
(A2LAMP, CAT12, TOP13, MSG:10/M645;1)
>>>>> Actually, there are color laser printers but they aren't cheap. You
""""" can get an Apple Color LaserWriter 12/660 for about $6000 (yep,
that's thousands, not hundreds.)
Laser printers are generally much faster than inkjets. I'd say 12 PPM
(pages per minute) is the average top speed with lasers, while 4-5 PPM is
the average with inkjets. Those are draft (low) quality speeds. Higher
quality settings and color will slow down the printing.

Okay; those printers are currently available.
> Now you'd mentioned the 500's RS interface is almost entirely
> incompatible with the Apple II's. Does the same hold true for the 600?
> Not needing a parallel card would certainly be a benefit.
The Epson 600 is per their web site (gack; Epson's web site is one of the
most un-usable web sites in the history of the universe. . . ) using about
the same serial interface as the 500.
Bottom line: you'll need either a parallel card or a serial to parallel
interface to use it with an Apple IIgs, and even then, it won't do anything
but be a paperweight with a GS/OS application, unless someone's willing to
write drivers for it.
OTOH, the Deskjet 340 is portable, reasonably priced, small, will do color
and black and white, and is compatible with the Apple II, Macintosh, and
Intel-type machines right out of the box. I recommended one of these to
Cindy Adams when she was looking for a portable printer for use with her
Powerbook sight unseen because I used one of its predecessors and found it
to be a fine printer. I got a chance to use it at KFest this past summer
and found it =better= than I ever imagined. I will buy one of these for my
own use soon, I was so impressed by it.
EVERYONE:
If you're going to buy an inkjet printer for use with the Apple IIgs, and
you buy anything -but- a Hewlett Packard inkjet, particularly ones listed
in the Deskjet stack as known to work with the Apple IIgs, you are setting
yourself up for a rather large amount of heartache. We have two wonderful
sets of GS/OS drivers for use with these printers as well as a couple of
dedicated vendors that produce them, a freeware HyperStudio stack that
discusses setting them up, and a wealth of knowledge on how to use them.
If you buy an Epson Stylus or Apple Stylewriter (other than the original),
you'll be left with no GS/OS drivers and very few (if any) users who have
experience with interfacing them in terms of both hardware and software to
an Apple IIgs. While Epson and Apple make excellent printers, HP printers
are at least as good. I work in a company that exclusively uses HP
printers, and I have bought no printer for myself other than HP for the
past four years, with absolutely no complaints whatsoever.
The preceeding Blatant Plug was brought to you with no financial rewards at
stake whatsoever (no, I don't own HP stock, I just love the printers :)

MIKE ON THE STATUS OF GSOFT Just to fill in the gaps, here's the current
""""""""""""""""""""""""""" status of GSoft:
Everything is done for the alpha software except parameter passing for
records and pointers, some clean-up for records and pointers, and the tool
interface (which requires support of record and pointer parameters.)
After that, I'll put together beta packages and brief documentation. Watch
for those here. I'll be beta testing as I finish the manuals (about 1000
pages all together, I expect) and will release once the manuals are done,
the bug reports become few or non-existant from beta testers, and I have a
chance to review the alpha version of the language for possible additions.
That's all going to take some time, and this isn't where my money comes
from. That's why it's hard to pin me down to a schedule. If I could work on
it full time, I'd say the end of September, but I can't. I'll probably just
spend weekends on it.

GNO/ME: THE REBIRTH The following message was posted on Delphi. It is

RE: GNO/ME (Re: Msg 431)
From: GLYNREADE To: ALL
X-Sender: bazyar@hypermall.com
Date: Sun, 10 Aug 1997 20:55:17 -0600
To: gdr@myrias.com
Subject: The End (and new Beginning) of GNO/ME
As the man behind Procyon Enterpsises Inc., a long-time Apple IIGS
developer and one of the last commercial developers for the platform, I
regret to announce the end to sales of my first product, the GNO
Multitasking Environment (GNO/ME).
With my last distributor, EGO Systems, closing its doors, I cannot justify
the time and expense of continuing to produce the software. I also didn't
feel it was fair to the customers to continue to charge them for the
product, when I would be unable to support them in the manner I would like,
due to my intense involvement in my new ISP business.
However, instead of simply stopping sales of GNO and letting the software
wander into oblivion, I am placing GNO into "freeware" status, and I am
also making available all source code to the 2.0.4 version to the public
and the development community.
I will still sell printed manuals to anyone who wants one, for $20 or so,
but this is just to cover printing and shipping costs. Purchasing a manual
will not entitle the buyer to support from me of GNO/ME.
Anyone who paid the normal $89 price to EGO Systems (or to me directly) for
GNO *will* continue to receive support from me, and I will rely partly on
the help of the "GNO-Devel" list for assistance in this support.
Speaking of that, the GNO-Devel list is headed by Devin Reade, and its
members are programmers who have the time and devotion to continuing to
develop the GNO system. To their capable hands I leave the sotware. The
first task of this group is to put together a GNO distribution based on the
latest ORCA/C and ORCA/C libraries. Devin will post followup info on csa2g
and any inquiries should be directred to him at <gdr@eddore.myrias.com> for
the moment.
Thank you all for your support in the past of my company and myself, and
best wishes to you all for the future!

Program Name: Marinetti
Filename: MARINETTI.BXY
Program Number: 30633
File Size: 44,800 bytes
Program Type: Control Panel (CDev)
Authors: Richard Bennett
Version Reviewed: 1.0b1 (15 Sep 1997)
File Type: freeware with restrictions
Requirements: Apple IIgs runnning System 6.0.1; 50k of boot
volume disk space; 30K of free RAM; modem;
Internet Service Provider with SLIP dial-up
connection
AT LAST, THE FUTURE IS HERE _Marinetti_ was the name of an Italian poet
""""""""""""""""""""""""""" of the earlier part of this century, but it's
also the name of the most exciting piece of new software that's come to the
Apple IIgs in years: a Control Panel that will bring the venerable IIgs up
to speed with the rest of the computing world, providing TCP/IP
(Transmission Control Protocol/Internet Protocol--say "Tee Sea Pea Eye
Pea") compatibility for the first time.
Demonstrated to the public for the first time by its author,
Australian Richard Bennett, at KansasFest 1997, _Marinetti_ is available
now, in a public beta form, from Genie A2, Delphi A2, and the _Marinetti_
home page (http://www.zip.com.au/~kashum/_Marinetti_). It is freeware, but
with certain restrictions regarding its distribution. It also must be
registered with the author--in its unregistered form, a rather inconvenient
dialog box reminding the user of the need to register pops up on a very
frequent basis.
The _Marinetti_ archive itself comes with the Control Panel, some
short but vital documentation, and _Telnet_, a simple telnet application
that will work in concert with _Marinetti_. Also required are an Apple
IIgs running System 6.0.1, a rather small amount of free boot drive space
and RAM, a modem, and an account on an Internet Service Provider which
allows SLIP (Serial Line Interface Protocol) dial up connections. Those of
you only with access to PPP (Point-to-Point Protocol) dial up connections
will need to wait until Richard incorporates support for that into
_Marinetti_.
Once the registration process is complete, the _Marinetti_ Control
Panel is simple but elegant in design. In fact, it incorporates the
functions of two separate Control Panels on the Macintosh (_InterSlip_ and
_TCP/IP_) into one package. The user needs to supply a set of instructions
(commonly called a "script") for starting and terminating a connection with
their ISP. These scripts instruct _Marinetti_ to dial the phone number of
the ISP, transmit the user's username and password, and capture the IP
address assigned to the user. Unfortunately, unlike similar programs on the
Macintosh, _Marinetti_ does not have an "auto-record" mode (similar to that
used with _ProTERM_ or _Spectrum_ to have the program "learn" your logons),
but the scripting language is very simple and fully documented.

PD_Q COMMENTS After figuring out and inputting my scripts, I moved the
""""""""""""" cursor on the screen to the "Connect" button and clicked.
In a few moments I heard the customary screeching and whistling of my USR
Courier modem. Shortly thereafter, I realized my Apple IIgs had
successfully connected to my ISP via a SLIP connection--finally, the
venerable Apple IIgs was directly connected to the Internet! I started the
provided _Telnet_ application, supplied the IP address of Delphi, and soon
was in the A2 Forum Conference room, chatting with other Apple II fanatics.
They may not have realized it, but I was totally exhilarated--at long last,
an error-free TCP/IP connection had me chatting with my long-time friends
in a virtual conference room, but instead of using a Macintosh, I was using
an Apple IIgs.
Marinetti did crash on me a number of times, but one must consider
that this is still pre-release software and the bugs are continuing to be
worked out. Additionally, while using the supplied Telnet application, one
must enter the destination address in its numeric form (such as
199.93.4.68) instead of its alphanumeric alias (delphi.com)--obviously the
alphanumeric name is easier to remember. There are currently just a few
applications available supporting _Marinetti_, the first of which is the
simple _Telnet_ program that came with the _Marinetti_ archive. It works,
and offers the intriguing possibilities of multiple concurrent telnet
sessions, but offers no file transfer, chat line, or terminal emulation
capabilities. It is a simple application meant to get us through the
period of time before the current trickle of _Marinetti_-savvy applications
becomes a flood.
Already, Ewen Wannop, author of _Spectrum_, has produced an XCMD,
known as _TopCat_, which allows _Spectrum 2.1_ to serve as a telnet client
(although without support for file transfer or terminal emulation). While
the _Spectrum Internet Suite_ World Wide Web browser does not currently
work with _Marinetti_, there is hope it will be modified to do such. In
the meantime, _SIS_ author Geoff Weiss has kept himself busy offering
_Marinetti_-savvy applications that provide the Whois, Finger, and Ping
functions. Many more applications are needed, including Internet Relay
Chat, File Transfer Protocol, and Electronic Mail clients. Weekend
programmers experienced in Applesoft BASIC eagerly await the pending
release of _GSoft_ BASIC from Byteworks, which will provide a
simple-yet-powerful interface to _Marinetti_.
While we await these applications--and others that only the
imagination limits--we can do so secure in the knowledge that the future
has arrived for users of the most powerful of the Apple II line. The poet
_Marinetti_ may have died in 1944, but the Control Panel _Marinetti_ (and
its author, Richard Bennett) will make sure the Apple II stays alive well
into the next millennium.

Top 10 Files for July
"""""""""""""""""""""
by Douglas Cuff
[D.CUFF]
This feature lists the ten most popular files for the month. To give
files a chance to seek their own levels, no files will be added to the list
until they've been in place at least a month. This month, we look at the
files uploaded 1-31 July 1997.
This isn't the Academy Awards ceremony, folks; it's more like the
People's Choice Awards (both of which are trademarked, by the way). The
Top 10 doesn't necessarily tell you what's new and interesting--what files
_you_ might find interesting--it simply tells you what files have been
downloaded a lot--what other people found interesting!
This month, GenieLamp A2 occupies three spots on the list, but we're
just counting that one file. Also, two different version of Crock O' Gold
count as just one file. We hope this explains why there are 13 files on
the Top 10 list.
Something else very interesting happened in July: the A2Pro library
was merged with the A2Pro library--over 1700 files--and meant that some of
the "old" files were new to some people. Two of the newly-merged A2Pro
files actually made it into the Top 10 for July!

>>> PART 6: THE ANNUNCIATORS - ACT 2 <<<
""""""""""""""""""""""""""""""""""""""""
SCALING UP Last time we looked at the way the Apple II can send a tiny
"""""""""" signal out into the real world by means of the annunciator
lines on the 16-pin game port. But before we use this small signal it must
be amplified to a useful level for operating an electrical device. The
signal must also be electrically isolated from this device to protect the
computer and the user in case of a component failure.
As I mentioned last time, I am going to describe how to build such an
isolating and amplifying circuit using a project from Vernier Software as a
basis. Such a circuit can be found in the Optically Isolated Circuits
project in "How to Build a Better Mousetrap" or in the Smart Battery
Charger project in "Chaos in the Laboratory". I have provided Vernier's
address at the end of this article for those who wish to get a copy of
these books.
In this installment I will look in general at the components that are
needed and what they do in the interface circuit. In the next article, I
will go into more detail on specific components and how to connect them.
OVERVIEW The circuit that I am about to describe fulfills all the
"""""""" required functions of an interface circuit between the Apple
II's annunciator line signals, and the demands of a real world electrical
device. However, this circuit can only operate devices which use fairly
low voltage direct current (DC). It can not drive a household 120 VAC
device and should never be used for such directly. In the next installment
I will discuss some additional interfacing devices which are required to
run high voltage AC devices. For now, the limits of this circuit are
dictated by the rating of the transistors used in the circuit. To be on
the safe side, one should not use it to operate anything using more than 12
volts DC. This provides a good margin of safety for all the components.
The circuit provides 3 levels of voltage and current amplification and
one stage of isolation. The circuit is called an Optically Isolated
Switch. The name comes from the fact that the transmission of the on/off
signal from the game port to the real world occurs by means of a beam of
light at one stage, with no direct electrical connection between the two
sides of the circuit (low power and high power). The actual device for
this optical transmission is an optoisolator chip. It is the optoisolator
which provides the electrical isolation of the circuit. The amplification
is accomplished using one TTL chip and two transistors. Let's see how this
is layed out. Follow along with a Vernier book if you have one at hand.
THE NITTY-GRITTY OF AN OPTICALLY ISOLATED CIRCUIT To start with, the
""""""""""""""""""""""""""""""""""""""""""""""""" on/off signal from the
game port is fed to an inverter IC. The function of this chip is to
provide enough current to operate the optoisolator. The game port signal
should not even be used to run the tiny light emitting diode (LED) in the
optoisolator. It is safer (for the computer at least) to use the inverter
between the two. The inverter is capable of providing more current than
the game port itself. When the game port annunciator turns on, it causes
the inverter to conduct electricity between two of its pins. These pins
are wired in such a way as to complete the circuit to the optoisolator's
LED when the inverter is switched on. Put simply, the annunciator turns on
the inverter, which in turn switches on the LED in the optoisolator.
The optoisolator is simply an LED and a phototransistor assembled in
one chip. When the LED lights up on one side of the circuit, it
illuminates a phototransistor on the other side. The phototransistor will
only conduct electricity when light is striking it. In this way it
functions as a remote on/off switch operated only by light. There is no
electrical connection at all between the LED and the phototransistor - only
a beam of light connects them. This is how the chip provides a very high
degree of electrical isolation between the low power and high power sides.
The phototransistor in the optoisolator is still a very low power
device and so requires a lot of amplification before real work can be done
with its signal. It is limited to a few milliamps of current at most.
When it turns on in response to light from the LED shining on it, this
small current is fed to the base connection of a small signal transistor.
The signal transistor is similar to the phototransistor in the
optoisolator except that it is turned on by a small electrical signal at
its base connection, rather than by light shining on it. When this small
electrical current is present at the base, the transistor conducts a larger
current between its two other connections (collector and emitter). So in
this way, a small electrical current switches on a much larger electrical
current. The signal transistor used in this circuit is capable of
switching currents of several hundred milliamps with only a few milliamps
being fed to its base from the phototransistor. This few hundred milliamps
is still a relatively small current, but is enough to switch a full size
LED on and off or to turn on a much larger transistor - a power transistor.
This is what we do with it.
The power transistor works in exactly the same way as the signal
transistor except that it requires a larger current at its base to switch
on. This current comes from the output of the signal transistor. The
power transistor can, in turn, conduct a much larger current between its
collector and emitter connections. The one used in this circuit is rated
for up to 5 amps. Now this is enough current to run some real world
devices. For example a power transistor can be used to switch on a
mechanical relay switch, a DC motor, a horn, a DC light bulb, or an
electromagnet. Now the possibilities for your Apple's tiny annunciator
output begin to open up!
So to review, here is the sequence of events which occur at the speed
of light in our optically isolated switch.
1) Your program turns on the Apple's annunciator output.
2) The annunciator turns on the inverter chip.
3) The inverter switches on the optoisolator's LED.
4) The optoisolator's LED turns on the optoisolator's phototransistor.
5) The phototransistor switches on the signal transistor.
6) The signal transistor turns on the power transistor.
7) The power transistor turns on a real world DC device of your
choosing.
.....and the hip bone is connected to the thigh bone and the .....
Oops, sorry I got carried away!
Seriously, this rather lengthy series of steps allows your line of
programming to switch something in your world on or off. Better yet, it
allows a few lines of your program to have the Apple decide for you when to
switch something on or off! Now you have the basis of real computer
interfacing.
All this is possible without the need for expensive cards or programs
for your Apple. Even with new parts from a retail electronics store, an
optically isolated circuit can be built for under $20. If you have access
to electronics discount, mail order, or surplus stores your optically
isolated circuit can be built for as little as $5. By putting four
identical circuits on one circuit board, you can switch four DC devices on
and off simultaneously, since the Apple has four independent annunciator
lines. Pretty impressive stuff!
Once again though, please remember that this circuit is limited to low
voltage direct current systems. Never connect this type of circuit
directly to 120 volt house alternating current. Destruction of the circuit
and your computer (and possibly you!) would be the result.
So now you have the secret of making your Apple do some real work for
you. Next time I will be getting into some details of particular parts
that are used in the circuits and the crucial things you need to know for
wiring them up.
