Gardener's Delight
~~~~~~~~~~~~~~~~~~
To a gardener tired of winter... receiving a seed catalog in the mail
is quite refreshing... an invitation to start planning this year's garden.
You will want to plant your favorites from past seasons... you will want
to try some of the new offerings. What changes you will make in the layout
of your garden space.
Growing plants from seed is similar to booting a computer... place the
seed where it is exposed to moisture, light, and the right temperature and
it germinates and grows to be a mature plant... fulfilling the plan
provided in the "ROM" (genes) of the seed.
The plant breeder has "programed" the new varieties of seeds you are
growing this year. (Introduced new characteristics... color, resistance to
disease, shorter growing season, etc.)
The gardener enables the good health of the plant by providing
adequate moisture and eliminating competition from weeds, protection from
insects, and controlling diseases.
The gardener is grateful to the plant breeder for developing the new
varieties of plants... the operator of the computer is grateful for the
programers who develop and improve the software necessary to the use of the
computer.

Old Computer Challenge 2007 Results
"""""""""""""""""""""""""""""""""""
Feb 3, 2007
The Old Computer Challenge is now well and truly finished... the number of
completed entries was slightly above my expectation, so I'm hereby
declaring the challenge an unqualified success. Here's a brief rundown of
who did what:
Bill Garber of Garberstreet Electronics distinguished himself by being the
first entrant to complete his challenge. Bill's contribution to the
retrocomputing world comes in the form of a slotless ROM switcher for the
Apple ][ and ][+. The ROM switcher can now be ordered from Bill's site.
http://www.garberstreet.com
Dale Goodfellow (aka wgoodf) took a shot at creating a short "film" with
his Apple //c... Using images created in Dazzle Draw and music played on
the //c, Dale's production is definitely unique.
http://80.192.34.202/Sample Files & Templates/rc07warmup.mov
Mark Stock (aka mmphosis) endeavored to create a "one well written Apple II
program" and learned a bit about hacking along the way. Mark's hacker
emblem program rocks, but his new-found hacker pride is the real
accomplishment.
http://geocities.com/mmphosis/apple2/contest/2007/old-computer-challenge.ht
ml
Lorance Stinson stepped up to the plate with his Hermes BBS running on a
Mac IIci. Although not a very busy board, it provided a hangout for the
more iron-willed of the challengers (mostly Dale and myself).
telnet://lorance.no-ip.org
Simon Williams (aka Luddite) managed to cobble-together a bit of music on
the Apple ][+. It may well be the first time the Apple II has been used in
Dub.
http://www.archive.org/details/Framebreaker-Serial_Dub
As an additional project he also put together what is surely the
"definitive" guide to authoring web content for the Contiki browser (on an
Apple II, of course).
http://contiki.ld8.org/GUIDE/INDEX.HTML
BigD went back in time for a few weeks of hardcore 68K Mac action, and left
a well written and informative blog in his wake. BigD's conclusion that the
challenge wasn't so tough after all should serve as encouragement to those
who are too timid to undertake such a test.
http://www.dustinr.com/retrochallenge/
In closing, I'd just like to thank all the contestants for their
contributions and I hope to see everyone back in the saddle for this
Summer's RetroChallenge! I mentioned at the start that there were no
prizes involved in the Old Computer Challenge, but I've decided that at the
very least everyone who completed their challenge will get an official Old
Computer Challenge T-shirt featuring Mark Stock's lo-res hacker emblem
design... now don't you wish you would have entered?

gcc Support for 65816?
""""""""""""""""""""""
A year or so ago there was some discussion about supporting the 65816
processor with gcc for Apple II development. Was there any progress made on
that front?
If not what are the choices?
I am aware of:
ORCA/C
MPW IIgs ORCA/C
MPW IIgs C
Are there any known issues with the MPW IIgs tools?
Glenn

"""""
gcc has had 65816 support for quite a while now--it doesn't look like that
the 65816 is being distributed in the latest binutils releases since there
is no owner. The first step to have IIgs usability is to add OMF support
to ld in binutils (it is really neat that Kelvin has worked on an OMF
linker written in Java, but that won't integrate into binutils).
If someone steps up to the plate to take ownership, I'll hack the 65816
assembly routines to give it pseudo 32-bit support for better portability
of existing applications. But without a portable linker, there is no point
to make any changes to the rest of binutils (I don't think any changes are
needed in gcc itself--binutils is where the cpu/os-specific code goes).
The ownership of the 65816/OMF in binutils means that every time a new
version of binutils is to be released, the 65816 and OMF code gets checked
to make sure that nothing broke.

It's generally considered better value to post these type of questions in a
public forum so that other people who are reluctant to post questions (or
who start reading later) can still get answers. You can always move to

There are a lot of people around who can help out with Orca/C. I'm one but
there are many others. (However I may not be as useful as in the past since
I don't have access to my GS as easily these days which makes

Okay - here goes
I have an application that has many files. There is the main app and a
bunch of sub programs. They all can be compiled, linked and loaded in one
shot or the main app can be compiled and the rest of the sub programs could
be compiled, linked then loaded in as needed and unloaded as they are
exited.
I understand there is a segment directive and I can specify dynamic (so the
segments are dynamic).
Some of these sub programs as spread over several c source files. So when
they are compiled they end up with there own object files.
I am not sure how to use the segment directive so that each sub program
ends up in a common dynamic segment.

I don't have tons of experience (none actually) in using dynamic segments,
but I would actually recommend using code resources instead of dynamic
segments; this gives you control over loading and unloading the code.
This way, you'd actually build each reloadable module using the #pragma RTL
pragma, then use the Resource Manager to load the code into memory and the
System Loader to relocate it. It's actually quite easy to do.

Orca/C Compile Command Problem
""""""""""""""""""""""""""""""
The compile command does not seem to take more than 255 characters of
input. If I feed it more it barfs to the monitor.
The Orca/C manual seems to infer that if your put your command in an exec
file that you can feed it up to 64K ref - page 113
I tried that but it still tanks.
I may try to set a variable in the exec file and supply the variable name
on the command ... might work ... unless the compile command only accepts
255 char.
Glenn
(a2retro, a2c.a2pro_developers, Jan 28 2007)

LOL! What the heck are you trying to feed to it!
I don't know the actual line length limitation, but are you sure you need
to do it the long way? It certainly wouldn't surprise me to learn that the
compiler itself couldn't handle a very long command line.
You have to remember that the Orca shell isn't Unix/Linux. There's lots of
hidden limitations, and some things that are definitely legal are still
flaky under some circumstances. Try to keep things very simple, very short,
etc. For example, try to cd to directories to avoid the need to specify
full pathnames for multiple files. Leave object files in the current
directory. Etc, etc.

Orca/c Tips
"""""""""""
Glenn,
I have a couple recommendations:
1) Use gno/me instead of the orca/shell. It's much more unix (BSD) like
than orca, has command line filename completion, and is much more pleasant
than orca's applesoft/vms/dos/cpm80 inspired syntax
2) Use occ. It's a front-end for orca/c (runs under orca and gnome) that
uses more standard commandline switches, and might be more graceful with
long lines.
3) Gnome includes dmake, which is much nicer than trying to build your own
makefile.
For your custom makefile, ProDOS's limited last modified time resolution
(1 minute is it?) might be causing you headaches.

Speaking of running in an emulator - I find that when running the orca dev

"""""
I seriously doubt that there is a problem with KEGS. Those invalid memory
access notices should give you an idea of how buggy Orca really is. KEGS
will always be better than a real IIgs to identify bad memory access (it
helps a lot when you are debugging your own code--sucks a lot using someone
elses). A real IIgs will gracefully use random values--making the problem
much harder to track down. Too bad there is no option other than Orca.
This is part of the reason why I had started to advocate that GNU tools
would be a good option for IIgs development. Orca can be dumped in favor
of an environment which has a much higher active development community. If
somebody wants to debug Orca/C, I have some source code on a 10-30 meg disk
image that I would love to see get compiled. I looked at the Orca/C source
and decided it wasn't worth my time to figure out (living in the world of
instant gratification does that to you).

I've used gno/me with sweet 16 and kegs. GNO does give the COP instruction
a workout, but if that was the issue, it would die fairly instantly.
Under kegs, the first time I login, gsh almost always hangs after the
message of the day is shown. I have to kill it using the GNO snooper CDA,
then login again (and everything is fine). Annoying, but not annoying

Orca/C Exec File to Help me Compile Programs
""""""""""""""""""""""""""""""""""""""""""""
I wrote this exec file to help me compile programs:
UNSET EXIT
SET opts cc=(-i"/CDEV:co:apps"-i"/CDEV:co:conf" -i"/CDEV:co:ctk"
-i"/CDEV:co:ek" -i"/CDEV:co:lib"-i"/CDEV:co:uip")
set list {1} {2} {3} {4} {5} {6} {7} {8} {9}
for i in {list}
echo Processing {i}
exists {i}.c
if {status} == 1
newer {i}.a {i}.c {i}.h
if {status} != 0
echo Compiling {i}.c
compile +T {i}.c {opts} KEEP=$ > {i}.log
else
echo {i} "Up to Date"
echo {i} > uptodate
end
else
echo {i} "Was not found"
echo {i} > notfound
end
end
so if the .c file exists and the .c or .h files are newer then the .a
file then compile the .c file
else print up to date or file not found
I get mixed results every time I run it
- some times it says the .c file is not found when it really is there
- sometimes it says it's up to date - which is what it should say every
time i run it after the first time if nothing else is modified
- most times it just compiles it anyway even if the .c or .h are not newer
anyone have any ideas on what is going on?

Ethernet Interface Code in Sweet16

It won't happen for version 2.0, which I'm hoping to release in the late

The publicly-shipping version of Sweet16 for BeOS actually hooks into the

That's true, but it's more work than I feel like going through, I expect.
Well... tell me this, what would be involved in emulating the Uther card,
for example? I don't know the I/O interface for it.

Hi Eric,
I would recommend you start by reading the application note for the 8bit
mode of the cs8900a. http://www.cirrus.com/en/pubs/appNote/an181.pdf
It gives you an idea of how the chip is used from an application point of
view and 8 bit data path.
That coupled with the Uther Link Layer source you can see what the minimum
part of the interface is that is required.
Init, receive packet and send packet.
There is source available in the Applewin project but again it is gpl and I
am not sure what license your sweet16 code is under ....

Sweet16 is freeware, no source distribution, so that wouldn't work.

I still think it's the best approach even if you can't leverage off of the
code in VICE/Applewin.
You might be able to get the authors permission to use the code anyway if
you ask... explaining it is for an application that is Freeware - no source
distribution due to other considerations.
I am sure *any* form of Ethernet support in Sweet16 would be great...

Slot Expander 1
"""""""""""""""
I just received the Slot Expander 1 boards I ordered from Vince Briel. Good
solid construction, and he thoughtfully included the IDE cable (nice touch)
all packaged up in a ziplock baggie. Now that's retro!

It's a 3 slot expansion board for the Apple 1, Replica 1 and clones. I
posted an article on it awhile back -

Would it be possible to add another item to this list? I would prefer to
know the last day that I visited A2Central.com, and not instead see
confirmation that yes I am actually here on this date.
If that is a bit unclear, I refer to the top right corner that currently
says that I last visited on Thursday, December 21, 2006.
Also, is there going to be any way to see the unread messages?

That bit of info will be 'vamped soon after the software upgrade - which
I'm hoping will be released around the New Year.

How do you read the board? HTTP, telnet or NNTP? That will help me best
with an answer.

I was reading through HTTP, but now I have MacSOUP up and running so now I

That is the best advice I can give anyone. The NNTP is sooo much nicer. I
prefer to view the telnet side as being the backwards compatibility mode
for people who want to connect using a real II, but newer technology
options exist that are certainly more efficient and convenient.

As a general rule, I hate NNTP clients. Even the "nice" ones get on my
nerves. I much prefer a nice web interface. I've finally caved and am set
up to use NNTP for this, because the web interface here is sadly not all
that great. :)
