If you have been reading Zmagazine
|
|
over the last few weeks, You will
|
|
notice that we have been publishing
|
|
articles in refrence to the ST
|
|
Transformer. This piece of software
|
|
emulates an ST into an 8 Bit. To
|
|
date this program has not been 100%
|
|
completed, But the author, Darek
|
|
Mihocka has been having troubles
|
|
getting permission from Atari to
|
|
persue his project. What I would like
|
|
to do is get a letter writing
|
|
campaign going so that we can get the
|
|
Atari higher-ups respond with a
|
|
reasonable explanation why Darek
|
|
can not be givin permission to use
|
|
the Atari ROM. To date we have no
|
|
response from any executive from
|
|
Atari.
|
|
|
|
Please help us out by writing a
|
|
letter to Atari. Please ask Atari
|
|
to respond openly in a message on
|
|
CompuServe, the Atari BBS, or any
|
|
BBS, to Darek with there point of
|
|
view on the matter. I have sent a
|
|
letter myself, and I will publish it
|
|
in next weeks edition. If you send
|
|
a letter, send a copy to me, I will
|
|
publish it here.

PRODUCT LINE
|
|
------------
|
|
|
|
At the January CES, Atari unveiled
|
|
our revamped product line for this
|
|
year. This is the most complete
|
|
lineup in the industry, running the
|
|
gamut from the very inexpensive XE
|
|
home computers to multi-megabyte
|
|
desktop publishing systems.
|
|
|
|
The high end products are the new
|
|
Mega ST computers. These models come
|
|
in 1, 2, and 4 megabyte
|
|
configurations. They come in a new
|
|
-stackable- housing with a detached
|
|
keyboard and a CPU box which includes
|
|
a 3.5- floppy drive and all the same
|
|
ports as the current ST's. New
|
|
features in the Mega ST computers
|
|
include an expansion bus with all the
|
|
pinouts of the 68000 chip as well as
|
|
some interrupt lines, a battery
|
|
backed-up realtime clock, and a
|
|
blitter chip as standard equipment.
|
|
These systems are currently scheduled
|
|
to begin shipping in Spring. Pricing
|
|
will be announced shortly.
|
|
|
|
Another new product announcement is
|
|
the Atari laser printer, priced at
|
|
the breakthrough price of under 1500.
|
|
The printer will plug into the DMA
|
|
(hard disk) port of ANY ST computer.
|
|
With a 520ST, the laser printer will
|
|
emulate a Diablo 630 and is also
|
|
capable of screen dumps. With larger
|
|
memory ST computers, the laser
|
|
printer will gain such features as
|
|
multiple fonts and dot-program-mable
|
|
graphics. Since the smarts of this
|
|
printer reside inside the ST, there
|
|
is no set protocol used with it - the
|
|
ST can be programmed to use virtually
|
|
and graphics protocol to control the
|
|
laser engine.
|
|
|
|
The current ST product line remains
|
|
as is, with some reductions in
|
|
pricing. The 1040ST is now $100
|
|
lower at retail than in 1986, while
|
|
last summer's special promotion for
|
|
520ST monochrome systems has been
|
|
reinstated. The SH204 hard drive is
|
|
also $100 lower than last year. One
|
|
improvement to the 520ST and 1040ST
|
|
this year will come with the release
|
|
of the -blitter- chip, which speeds
|
|
the performance of graphics and text.
|
|
This new chip will be available as a
|
|
$120 upgrade to the current ST line,
|
|
consisting of the blitter itself
|
|
which attaches to the 68000 CPU chip,
|
|
as well as a set of replacement ROM
|
|
chips which provides software
|
|
compatibility, improved performance,
|
|
and some bug fixes. It is possible
|
|
that a later revision of the ROMs
|
|
will be made available later in the
|
|
year to further improve and correct
|
|
system performance.
|
|
|
|
The XE product line continues into
|
|
1987 as well. Atari is making a
|
|
strong effort to improve this line by
|
|
releasing the XEP80 (an 80-column
|
|
adapter) and by making the new SX212
|
|
modem compatible with this line as
|
|
well as the ST line. New software
|
|
titles continue to be released for
|
|
the XE as well.
|
|
|
|
BITS AND PIECES
|
|
---------------
|
|
|
|
ST BASIC is still alive and is
|
|
undergoing internal testing. once
|
|
we're satisfied that it is bug-free,
|
|
we'll release it. In the meantime,
|
|
there are some good BASICs out there.
|
|
For instance:
|
|
|
|
-GFA BASIC-
|
|
Michtron
|
|
576 South Telegraph Hill
|
|
Pontiac, MI 48053
|
|
(313)334-5700
|
|
* Michtron also carries -GFA
|
|
COMPILER- which makes this already
|
|
fast BASIC even faster.
|
|
|
|
-AC/BASIC-
|
|
Absoft Corp.
|
|
4268 North Woodword Avenue
|
|
Royal Oak, MI 48072
|
|
(315)549-7111
|
|
|
|
-HENRY'S FUNDAMENTAL BASIC-
|
|
Philon, Inc.
|
|
641 Avenue of the Americas
|
|
New York, NY 10011
|
|
(212)807-0303
|
|
|
|
-1ST WORD PLUS- - There has been a
|
|
snag in progress having to do with
|
|
our contract with GST, so we're not
|
|
expecting to release -1ST WORD PLUS-
|
|
in the near future.
|
|
|
|
-MICROSOFT WRITE-, which is still in
|
|
beta testing, has been getting raves
|
|
at the Atari offices. Atari expects
|
|
it to be out in the second quarter of
|
|
1987.
|
|
|
|
-SX212 1200 BAUD MODEM- - The SX212
|
|
will not need an 850 interface module
|
|
in order to be connected to the Atari
|
|
8-bit computers. It has an SIO
|
|
connector on the back, in addition to
|
|
the standard modem connector. Atari
|
|
will be selling a special SIO and
|
|
terminal package (SXExpress, a
|
|
special version of Express, the most
|
|
popular 8-bit terminal program) for
|
|
8-bit users. Please note that this
|
|
will be a separate package, and is
|
|
not included with the SX212.
|
|
|
|
Of course, the SX212 can be used with
|
|
the 850 interface and any terminal
|
|
program which uses it. For those who
|
|
don't have an 850, ICD is marketing a
|
|
device called the -PR CONNECTION-,
|
|
which works identically to the 850.
|
|
|
|
-NEW SOFTWARE FOR THE XEP80 80-COLUMN
|
|
CARD- - New versions of -SILENT
|
|
BUTLER- and -ATARIWRITER PLUS- for
|
|
the 80-column card that is coming out
|
|
for the 8-bit machines are in
|
|
production. The new -SILENT BUTLER-
|
|
will work in both 40- and 80-column
|
|
modes; however, those people who wish
|
|
to use -ATARIWRITER PLUS- will have
|
|
to use the version for the mode
|
|
they've got - that is, 40-column
|
|
users will have to use the 40-column
|
|
version and 80-column users will have
|
|
to use the 80-column version. The
|
|
two are not interchangeable.
|
|
|
|
-LASER PRINTER- - Many of you have
|
|
asked if the new laser printer will
|
|
have loadable fonts. The answer is:
|
|
sorta.
|
|
|
|
Other manufacturers' laser printers
|
|
are expensive because they actually
|
|
have a computer inside to provide all
|
|
the wonderful things laser printers
|
|
provide, including the capability to
|
|
load fonts.
|
|
|
|
Atari will use the power and speed of
|
|
the Mega ST as the engine for the new
|
|
laser printer. You will be able to
|
|
load fonts into the ST just as you
|
|
would a laser printer and voila, you
|
|
can print fonts.

Xx TECHNICAL TIPS
|
|
.......XL Ramdisk........
|
|
_____________________________________
|
|
|
|
Those of you with 130XEs already know
|
|
the power of the RAMdisk. A RAMdisk
|
|
configures as part of the computer's
|
|
memory so it can be treated just like
|
|
a disk drive, boosting speed and
|
|
convenience (at the cost of available
|
|
memory, of course).
|
|
|
|
Good news! There is a chunk of unused
|
|
RAM area in the 800XL/1200XL that
|
|
sits under the ROM and is used only
|
|
occasionally by BASIC XE and a few
|
|
other programs. You can renovate it
|
|
into a mini RAMdisk with the
|
|
following quick steps:
|
|
|
|
1) Boot DOS 2.5 with BASIC
|
|
2) Type the following:
|
|
|
|
POKE 1802,PEEK(1802)+128
|
|
DOS
|
|
L
|
|
RAMDISK.COM
|
|
I
|
|
8
|
|
Y
|
|
B
|
|
POKE 5439,56
|
|
|
|
The DOS menu (which is actually
|
|
called DUP.SYS) will now come up
|
|
instantly, loaded from a RAMdisk
|
|
known to your computer as drive 8.
|
|
You can put away your DOS disk. This
|
|
quick RAMdisk is limited to 15K (even
|
|
less once DUP.SYS is resident), and
|
|
that is not enough room to cache a
|
|
complex program or reams of data.
|
|
But if it fits, any chunk of code can
|
|
be kept there for instantaneous
|
|
RAMdisk retrieval.
|
|
|
|
This XL RAMdisk tip ONLY works with
|
|
the Atari 1200XL, 800XL, expanded
|
|
600XL, and 65XE computers.)

After reading and building both the
|
|
800/288K upgrade from (D.G.Byrd), and
|
|
the 800XL/256K upgrade from C.Buchholz.
|
|
I decided that there also had to be a
|
|
way to upgrade the 130XE. There is,
|
|
and thanks to the -Freddie- chip
|
|
(CO61991) this modification is much
|
|
easier to do than either of the other
|
|
upgrades.
|
|
|
|
To do the upgrade you will need a:
|
|
|
|
Soldering iron
|
|
De-soldering tool
|
|
Some fine wire.
|
|
See the parts list for the chips
|
|
needed.
|
|
|
|
First, remove both the case and the
|
|
metal shield to get down to the
|
|
mother-board. Then remove the eight
|
|
ram-chip U26 thru U33(MT4264). They
|
|
are the row closest to the TV RF
|
|
module. Next, install Z2 thru Z9 in
|
|
the place of U23 thru U33. These are
|
|
the 256K ram-chips. You can solder
|
|
them to the mother board, or use
|
|
sockets. Now take a piece of wire
|
|
approx 12 in. long and run a jumper
|
|
from pin one on each of the 256K ram
|
|
-chips to the next. After you do
|
|
this the wire will be connected to
|
|
pin 1 on Z2 thru Z9 and you should
|
|
have about 6 inches left over. Do
|
|
this on the rear of the mother board
|
|
and then snake the wire thru the
|
|
large hole near the ram chips.
|
|
|
|
Next, desolder and remove U23
|
|
(CO14795), and replace it with a 40
|
|
pin socket. Bend up pins 15 and 16
|
|
on U23 and insert it in the socket
|
|
you just installed. Take Z1(74LS158)
|
|
and bend up all the pins on it except
|
|
pins 8 and 16. Put this -piggy-back-
|
|
on top of U20(HD14050) and solder
|
|
pins 8 and 16 of Z1 to pins 8 and 16
|
|
on U20. Now solder a short jumper
|
|
from pin 15 on Z1 to pin 8 of Z1.
|
|
|
|
Now, take a piece of wire about 4 in.
|
|
long solder one end to pin 30 on the
|
|
chip marked -CO14805- on the mother
|
|
board, and the other to pin 1 on Z1.
|
|
Next solder a wire to pin 15 (one of
|
|
the two you bent out) of U23 and
|
|
connect the other end to pin 2 on Z1.
|
|
Solder a wire to pin 16 on U23 and
|
|
connect the other end to pin 3 on Z1.
|
|
|
|
Take R1(33 ohm) and trim the leads to
|
|
about 1/4 in. Take the wire you
|
|
connected to pin one on the 256K ram-
|
|
chips and solder it to one end of R1,
|
|
solder the other end of R1 to pin 4
|
|
on Z1. Re-assemble the RF shield and
|
|
case and you are done.
|
|
|
|
PARTS LIST.
|
|
-----------
|
|
Z1 74LS158(2 to 1 Multiplexer)
|
|
Z2-Z9 41256 dynamic RAM(150ns)
|
|
R1 33 ohm 1/4 watt resistor.
|
|
1 40 pin socket.
|
|
8 16 pin sockets(optional).
|
|
|
|
This upgrade has been built and
|
|
tested on a BBS, it has run for days
|
|
on end without a memory loss or
|
|
error. If you need help or more
|
|
information feel free to call the
|
|
Peanut Gallery (408)-384-3906. 24HR,
|
|
300/1200 Baud. Leave mail to the
|
|
Sysop(thats me). Good luck and let me
|
|
know if you write a better handler.
|
|
|
|
If you are using MYDOS 3.016 and wish
|
|
to use Basic XE and a ram-disk at the
|
|
same time, boot DOS and poke 5275,163
|
|
and 5324,16. Go to DOS and write the
|
|
new DOS. This will keep the two from
|
|
-bumping- into each other. A similar
|
|
poke can be done to DOS 2.5, it is
|
|
poke 4838,163.
|
|
|
|
The handler I have will set up 192K
|
|
of the extra ram as 2 SD ramdisks or
|
|
1 DD ramdisk.
|
|
|
|
If you are a hot-shotprogrammer (Im
|
|
not) I think a print spooler that
|
|
uses part of this ram would also be
|
|
very nice. This mod is easy to do and
|
|
perfect for running a BBS. One note,
|
|
on compuserve there is a mod by Rich
|
|
Andrews which should not be confused
|
|
with this one, his uses 33 new chips
|
|
and mine uses 9 new chips. Have fun.

The 130XE/576K upgrade
|
|
.........by Scott Peterson...........
|
|
........Copyright (C) 1986...........
|
|
_____________________________________
|
|
Here we go again, this time I
|
|
recommend you have some electronics
|
|
experience if you wish to preform the
|
|
upgrade. Some of the work is
|
|
duplicated from the 320K upgrade so
|
|
320XE owners will not have as much
|
|
work to do. One other point, when in
|
|
the 576K mode you MUST use some sort
|
|
of basic cart. as you lose the
|
|
internal basic, this is only in the
|
|
576K mode, in the 130XE mode internal
|
|
basic will function normally.
|
|
|
|
TOOLS NEEDED;
|
|
|
|
To preform this upgrade you need the
|
|
following;
|
|
|
|
Low wattage fine tip soldering iron.
|
|
Vacuum de-soldering tool(like Radio
|
|
Shack PN#64-2098).
|
|
Some 30-gauge wire
|
|
(Radio Shack PN#278-501).
|
|
|
|
#2 phillips head screwdriver.
|
|
Heat-shrink tubing, 1/8 in. Dia.
|
|
Also a pair of small needle-nose
|
|
pliers and a small flat tip
|
|
screwdriver are handy.
|
|
|
|
PARTS NEEDED;
|
|
|
|
Z1 74LS158
|
|
Z2-Z17 41256(150ns.)
|
|
Z18 74LS138
|
|
Z19 7432
|
|
R1-R2 33 ohm 1/4 watt resistor.
|
|
S1 Micro-mini DPDT switch
|
|
(like Radio Shack PN#275-626)
|
|
|
|
Remove the 130XE case and metal RF
|
|
shield to get down to the mother
|
|
board.(320XE users go to step two).
|
|
|
|
STEP ONE:
|
|
|
|
Now de-solder and remove the eight
|
|
ram chips U26 thru U33(MT4264). They
|
|
are the row closest to the TV RF
|
|
module (do NOT use solder wick, the
|
|
circuit board of the 130XE has very
|
|
weak runs and they will pull loose if
|
|
not completely de-soldered). Replace
|
|
these with the 16 pin low profile
|
|
sockets. Take a piece of wire approx
|
|
12 in. long and run a jumper from pin
|
|
1 of each socket to the next. When
|
|
you are done the wire should be
|
|
attached to pin 1 of each of the new
|
|
sockets and you should have about 6
|
|
inchs left over. Do this on the rear
|
|
of the mother board and then snake
|
|
the wire thru the large hole near the
|
|
ram chips.
|
|
|
|
Next, desolder and remove U23
|
|
(CO14795), and replace it with a 40
|
|
pin socket. Bend up pins 15 and 16
|
|
and insert it in the socket you just
|
|
installed. Take Z1(74LS158) and break
|
|
off pins 5,6,7,9,10,11,12,13,14. Bend
|
|
up the other pins on it except 8 and
|
|
16. Put this -piggy back- on top of
|
|
U20 (HD14050, or 4050 - located just
|
|
to the right of C50) and solder pins
|
|
8 and 16 of Z1 to pins 8 and 16 on
|
|
U20. Now take a short jumper from pin
|
|
15 on Z1 to pin 8 of Z1. Take a piece
|
|
of wire about 4 in. long, solder one
|
|
end to pin 30 on the chip marked
|
|
-CO14805- on the mother board, and
|
|
the other end to pin 1 on Z1. Next
|
|
solder a wire to pin 15(one of the
|
|
two you bent out) of U23 and connect
|
|
the other end to pin 2 on Z1. Solder
|
|
a wire to pin 16 on U23 and connect
|
|
the other end to pin 3 on Z1.
|
|
|
|
Take R1(33 ohm) and trim the leads to
|
|
about 1/4 in. Take the wire you
|
|
connected to pin 1 of the ram chip
|
|
sockets and solder it to one end of
|
|
R1, solder the other end of R1 to pin
|
|
4 on Z1.
|
|
|
|
STEP TWO:
|
|
|
|
Slide the mother board back into the
|
|
bottem half of the plastic case (do
|
|
not use the RF shield, you must be
|
|
able to get at the mother board), and
|
|
attach the keyboard. It will rest
|
|
above the mother board without
|
|
touching it. Test all 41256 ram chips
|
|
by putting one set of 8 in the
|
|
sockets and using the handlers (or
|
|
DOS's), and then the next. After
|
|
testing all ram chips remove them all
|
|
from the sockets, and take 8 of them
|
|
and cut about half of pin 15 off of
|
|
each one. Only the -fat- part of pin
|
|
15 should be left. After doing this
|
|
you have to -piggy back- the 8 256K
|
|
ram chips with the short pin 15's on
|
|
top of the other 8 256K ram chips.
|
|
Now solder all the pins together on
|
|
the stacked ram chips except for pin
|
|
15, it should not be touching the
|
|
other pin 15, make sure you have them
|
|
going pin 1 to 1, pin 2 to 2, ect.
|
|
When you get done you will have 8
|
|
sets of Piggy backed 256K ram chips.
|
|
Now take a piece of wire about 16 in.
|
|
long and run a jumper from pin 15 to
|
|
the next one on all the top 256k
|
|
DRAM's, leaving about 1 inch between
|
|
each ram chip. Put these stacked ram
|
|
chips into the 8 sockets you
|
|
installed earlier. Take Z18 (74LS138)
|
|
and bend up all the pins except 8 and
|
|
16, cut the pins you bent up in half
|
|
so only the fat part is left, and
|
|
solder pins 8 and 16 to pins 8 and 16
|
|
of the other 74LS138 right below the
|
|
U23(CO14795). Take Z19 and bend up
|
|
all pins except 7 and 14, once again
|
|
cut all the pins you bent up in half
|
|
and solder pins 7 and 14 to pins 7
|
|
and 14 of the 74LS08 right below U23.
|
|
|
|
Take the wire you jumpered earlier to
|
|
pin 15 of Z10 thru Z17(the upper row
|
|
of 256K ram chips) and go out 2 in.
|
|
and cut the wire, now install R2 (33
|
|
ohm) between this cut. Place a piece
|
|
of heat shrink tubing over R1 and
|
|
make sure no wire is exposed and heat
|
|
it with a lighter. Take the other end
|
|
of this wire and connect it to Z18
|
|
pin 14. Find the 2 33 ohm resistors
|
|
just to the right of U28(one of the
|
|
ram chips you socketized). The upper
|
|
one of the 2 is R111, desolder the
|
|
right leg of it and bend it up. Take
|
|
a piece of wire and solder it to the
|
|
land where you just removed the leg
|
|
of R111. Connect the other end to Z18
|
|
pin 4. Trim back the leg of R111 and
|
|
solder a wire to it, slip a piece of
|
|
heat shrink tube over it and heat it
|
|
up. Now connect the other end to Z18
|
|
pin 12. Take a short wire and run a
|
|
jumper from pins 1 and 16 of Z18.
|
|
Take another short wire and connect a
|
|
jumper from pins 3,5, and 8 of Z18.
|
|
Now connect a wire from Z18 pin 2 to
|
|
Z19 pin 3.
|
|
|
|
Find the wire you installed from U23
|
|
pin 15 to Z1(74LS158) pin 2 and
|
|
desolder it from U23. Take it and
|
|
reconnect it to Z19 pin 11. Ok, now
|
|
pry U23 (CO14795) back out of the
|
|
socket and bend up pin 11, plug it
|
|
back in. Run a jumper from pins 1 and
|
|
4 of Z19, and another jumper from
|
|
pins 10 and 13 of Z19. Connect a wire
|
|
from U23 pin 11 to Z19 pin 1, and
|
|
from U23 pin 15 to Z19 pin 13. Now
|
|
connect a wire from Z19 pin 8 to the
|
|
right side of the 3.3K ohm resistor
|
|
marked R206 (located at the bottom
|
|
right of U23). Connect a wire to Z19
|
|
pin 6 and run it to pin 18 of U3
|
|
(CO61618). Now comes the tricky part,
|
|
drill a small hole(1/4 in. or so,
|
|
depending on the switch size) at the
|
|
rear right on the back of your 130XE.
|
|
Take the small DPDT switch (S1) and
|
|
install it in the hole. Now connect
|
|
it as shown (make sure the switch
|
|
DOESNT have a center off position);
|
|
|
|
S1(rear)
|
|
U23 ________ U23
|
|
pin 20 ----|-O O-|----- pin 1
|
|
| \ / |
|
|
Z19 ---|-O \/ O-|--- Z19
|
|
pins 2+12 | /\ | pins 5+9
|
|
| / \ |
|
|
| O O |
|
|
|________|
|
|
Note: where the wires cross in the
|
|
middle, they are NOT connected. Make
|
|
the connection from the switch to U23
|
|
on the rear of the mother board. Well
|
|
that's it(thank god). Now re-assemble
|
|
the computer, being carefull not to
|
|
break any wiring going to the switch.
|
|
You should now have in one switch
|
|
position a 100% compatable 130xe, and
|
|
in the other you have a 576K 130XE
|
|
that does not have Antic memory
|
|
enhance mode and also can-not use
|
|
internal basic. In the 130XE mode you
|
|
gain 64K as bit 6 of the PIA can
|
|
still be used. The following page
|
|
list of the bit table and numbers to
|
|
be used in location 54017 (PORTB).

Once again, if you need help call the
|

Peanut Gallery BBS (408)-384-3906. If
|
|
you want a mailer of all the upgrades
|
|
I have as well as a disk with

|
|
|
|
This includes the 800 288K upgrade by
|
|
D.G.Byrd, the 800XL/256K C.Burchholz,
|
|
the 130XE/320k upgrade and anything
|
|
else I finish. Good luck, and have
|
|
fun.
|
|
|
|
There is a version of MYDOS to
|
|
support this mod, its called 4.1A and
|
|
will run up to 32 16K banks. At this
|
|
time ICD is working on a RD.COM file
|
|
to support this. Also I have written
|
|
a machine lang. tester that will load
|
|
and test all 32 banks of memory to
|
|
insure that they are there and work.
|
|
Wonder how long it will take Jay
|
|
Torres to copy this one.
|
|
Good luck

The final step, the 1088XE
|
|
|
|
Well, this is it for me, the last
|
|
installment on the 130XE. I have not
|
|
built this mother, but the theory
|
|
behind it has been built and tested.
|
|
This doc assumes you have already
|
|
built and tested a 576K 130XE. To
|
|
finish it you will need the following
|
|
parts:
|
|
|
|
Quantity Part No. Description.
|
|
--------------------------------
|
|
16 41256-15 256K DRAM'S
|
|
1 7432 Quad OR gate
|
|
1 7404 Quad invert
|
|
buff.
|
|
2 33 omh Resistors
|
|
1 Small piece of PC board.
|
|
---------------------------------
|
|
|
|
Note: On the 74 series, you can sub
|
|
them with 74LS series chips,
|
|
they use less power.
|
|
|
|
Tools:
|
|
|
|
Nothing fancy, a fine tip soldering
|
|
iron and some fine wire,etc.
|
|
|
|
Mount the 7404 and the 7432 on a
|
|
small PC board(1in. X 2in.). Connect
|
|
together pin 14 on the 7432 and pin
|
|
14 on the 7404 with a length of fine
|
|
wire. This is the +5v supply to the
|
|
chips, connect it to pin 14 of any 14
|
|
pin chip in the 130XE any 14 pin chip
|
|
in the 130XE or pin 16 of any 16 pin
|
|
chip in the 130XE.
|
|
|
|
Next connect a length of wire to pin
|
|
7 of the 7432 and pin 7 of the 7404.
|
|
This is ground for the two chips,
|
|
connect it to pin 7 of any 14 pin
|
|
chip in the 130XE or pin 8 of and 16
|
|
pin chip. Next, take U23(U23) out of
|
|
the socket and bend up pin 17,
|
|
reinsert it in the socket. Solder a
|
|
piece of wire to pin 17 of U23, and
|
|
connect it to the 7432 pins 2 and 5.
|
|
Next connect a wire to pin 14 on U23
|
|
(PIA) run it to pin 1 on the 7404 and
|
|
pin 1 on the 7432. Now connect a wire
|
|
from the 7432 pin 6 to pin 17 of the
|
|
socket U23 is in. Find the 74LS138
|
|
you piggy backed to the mother board
|
|
when doing the 576k mod. Remove the
|
|
jumper from pins 1 and 16. Solder a
|
|
wire from pin 3 of the 7432 on the PC
|
|
board to pin 1 of the piggybacked
|
|
74LS138. Put some double backed tape
|
|
on the PC board and stick it
|
|
somewhere on the mother board of the
|
|
130XE.
|
|
|
|
RAM-CHIP installation(lots of them!)
|
|
Take the 16 new ramchips and cut pin
|
|
15 on all of them in half so only the
|
|
'fat' part is left. Now, you have to
|
|
piggy back them on-top of the 64K
|
|
drams(the left-most row of chips).
|
|
Solder in 8 of them, connecting all
|
|
pins except pin 15, then connect a
|
|
jumper to pin 15 of each new ramchip.
|
|
Make sure you have about a foot left
|
|
over. Solder in the next 8 doing the
|
|
same thing. When you get done you
|
|
should have 2 new rows of 256k DRAM's
|
|
soldered in on-top of the 64K DRAM's,
|
|
with a 2 wires, one connected to all
|
|
pin 15's of the middle row and
|
|
another connected to all the pin 15's
|
|
of the top row. Take one wire and go
|
|
out a few inches and install a 33 ohm
|
|
resistor in-line, cover with heat
|
|
shrink tubing and do the same to the
|
|
other wire. Connect one wire to pin
|
|
15 of the 74LS138 and the other to
|
|
pin 13 of the 74ls138.
|
|
|
|
Your done!!! Sorry, as of right now
|
|
I know of no software to run on this
|
|
I release this doc file with out
|
|
testing it. I have built the small
|
|
circuit on the PC board and connected
|
|
it in a 576K 130XE and used it to
|
|
move the memory instead of the basic
|
|
control bit, so I know it works, this
|
|
little circuit works in both the
|
|
800XL or 130XE if you have something
|
|
you would like to use bit 7 (self
|
|
test bit) for. If you have
|
|
constructed a 320XE mod and would
|
|
like to use bit 7 instead of bit 5,
|
|
this is a good way to do it. A
|
|
warning though, you will regain your
|
|
antic enhanced mode but software
|
|
written for the original 320XE mod
|
|
will not run on it after you do it.
|
|
If you are trying to figure out your
|
|
memory control bits here's a cheat
|
|
sheet.
|
|
|
|
Decimal 128 64 32 16 8 4 2 1
|
|
---------------------
|
|
Control bit 7 6 5 4 3 2 1 0
|
|
---------------------
|
|
|
|
Just find you control bits and add
|
|
them up to figure out the decimal
|
|
control number. When you get done you
|
|
should have in one switch position
|
|
a 130XE with 320K,built in basic and
|
|
antic enhanced mode. In the other
|
|
position you lose antic enhanced
|
|
mode, internal baisc but you have
|
|
1088K of memory, 64 banks of 16K.
|
|
By the way, typing BYE will still
|
|
throw you into the self test mode
|
|
(bit 7 still works). If anyone
|
|
complete's this monster, please call
|
|
my BBS at (408)-384-3906, or leave
|
|
me a message at compuserve.
|
|
Good Luck

announced the addition of the -ST
|
|
SOUND DIGITIZER- and -ST VIDEO
|
|
DIGITIZER- to its product line for
|
|
the Atari ST. The two low-cost
|
|
hardware peripherals bring the world
|
|
of sight and sound directly into the
|
|
heart of the computer. In addition
|
|
to the new products announced,
|
|
Navarone manufactures -TIMEKEEPER-, a
|
|
battery-backed clock/calendar with
|
|
built-in extender slot for the Atari
|
|
ST.
|
|
|
|
Easy-to-use GEM-based software comes
|
|
with each digitizer and -TIMEKEEPER-

TACKLE BOX ST:
|
|
|
|
A utility for Personal Pascal users.
|
|
|
|
If you are looking for complete
|
|
documentation on GEM calls for
|
|
Personal Pascal, then look no more!
|
|
Tackle Box ST contains everything you
|
|
need to make calls to GEM. If you are
|
|
a novice programmer, this utility may
|
|
be all the help you need to
|
|
understand GEMDOS. Be forewarned, IT
|
|
DOES NOT TEACH YOU PASCAL! If you are
|
|
an advanced programmer, use this
|
|
utility as a quick reference to
|
|
GEMDOS.
|
|
|
|
This utility can be used to decode
|
|
'C' type GEMDOS statements. This
|
|
utility was written as a service to
|
|
Pascal users. In as much, we would
|
|
like to see a standard emerge for
|
|
GEMDOS Procedure or Function names.
|
|
In making the AES and VDI library
|
|
calls for example, we have stuck to
|
|
the 'C- convention of naming
|
|
Procedures and Functions. Therefore,
|
|
if you run across a piece of 'C'
|
|
code, you can use our book as a
|
|
reference guide to their call and in
|
|
turn, make the same call in Pascal.
|
|
Once these standards emerge, GEMDOS
|
|
should become a little more self-
|
|
documenting. If you do not agree with
|
|
our reasoning, don't despair, we give
|
|
you all the documentation and source
|
|
code to change the name to whatever
|
|
you like!
|
|
|
|
We are also in the process of writing
|
|
a newsletter called TB Newsletter.
|
|
This letter will actually be on disk
|
|
at a cost of $3.50 per disk(remember,
|
|
you get the first 3 issues free with
|
|
the purchase of Tackle Box ST). This
|
|
newsletter will be a vehicle for
|
|
updating Tackle Box ST, will be a
|
|
forum for discussing new Atari
|
|
developments, as means for
|
|
distributing public domain programs
|
|
and finally as a way for users to get
|
|
to know each other. We are accepting
|
|
articles, demo programs and comments
|
|
at this time. Your help in 'getting
|
|
the word 'out' is much appreciated by
|
|
us and all those that you may help.
|
|
|
|
Please send your programs to us on a
|
|
diskette and please include the
|
|
source code so others may benefit.
|
|
|
|
All topics are welcomed!
|
|
|
|
TACKLE BOX is compatible with
|
|
Personal Pascal Version 1.11 and
|
|
lower. Updates will be made, if
|
|
needed, as newer releases of Personal
|
|
Pascal are made!
|
|
|
|
TACKLE BOX ST WILL BE AVAILABLE 16

COMPUTING, (C) April 1987 By John J.
|
|
Anderson (CIS# 76703,654)
|
|
|
|
At COMDEX (Computer Dealers
|
|
Exposition) and CES (Consumer
|
|
Electronics Show) - both trade shows
|
|
held in Las Vegas recently - desktop
|
|
publishing was a buzzword. Good
|
|
desktop programs were in abundance
|
|
for the ST. CAD (Computer Aided
|
|
Design) was another big idea.
|
|
|
|
Many exhibitors at the Atari booth
|
|
had a 1040ST, a hard drive, and a
|
|
laser printer. There printers were
|
|
lent by QMS, Hewlett-Packard, Canon,
|
|
and others. Atari itself showed a
|
|
laser printer it plans to sell for
|
|
under $1,500. Two WYSIWYG (What You
|
|
See Is What You Get) publishing
|
|
packages, -Publishing Partner- from
|
|
Softlogik (314-894-8608; $149.95) and
|
|
-Fleet Street Editor- from
|
|
Mirrorsoft, a British company
|
|
(011-44-1-377-4600/4384; $172.50),
|
|
attracted lots of attention. Also
|
|
shown was the new -Typesetter Elite-
|
|
from XLEnt Software (703-569-8881;
|
|
$49.95) and the command-driven
|
|
-LaserType- from Softlab
|
|
(801-628-4969; $279).
|
|
|
|
*** WHAT A CAD! ***
|
|
|
|
Progressive Computer Applications had
|
|
its -Graphic Artist- program
|
|
(301-340-8398; $199.95) working with
|
|
a huge IOLION (Houston Instruments
|
|
-compatible) plotter, creating all
|
|
kinds of architectural designs, page
|
|
layouts, and pictures. Also in the
|
|
CAD area, Foresight Resources Corp.
|
|
had a top-notch package called
|
|
-Drafix 1- (1-800-231-8574; $249)
|
|
According to Foresight, it runs as
|
|
fast on an ST as it does an IBM PC/AT
|
|
(running at 8 MHz with a math
|
|
co-processor!).
|
|
|
|
Generic Software's -FirstCADD-
|
|
(1-800-228-3601; $49.95) was also a
|
|
popular exhibit, as was Abacus
|
|
Software's -PC Board Designer-
|
|
(616-241-5510; $195).
