Hi Everyone,

I recently built a CP/M-68K system (the 68K-MBC), and I would very much like to have a FORTRAN compiler running natively on the system.
Searching the Internet, it seems that some FORTRAN compilers were made for CP/M-68K.

I can't find one on the "usual" CP/M sites and archives, though.

Maybe you can help me locate one?

Best regards,
Mogens

Hi Mogens --

The best archive for CP/M-68K stuff, and lots of Cromemco stuff as well, is the old Maben site. Marcus moved it to GitHub, and made it inaccessible unless you are granted permission. I find that getting permission to the GitHub repository is a *real*
challenge. Your experience might vary?

The files Marcus moved to the GitHub site are almost exclusively limited to Cromemco stuff. Cromemco's Fortran compilers for Cromix are archived there, but no software for CPM-68K.
To the best of my knowledge the only Fortran compiler for CPM-68K was produced by a company called "Silicon Valley Software", and I have never seen copy of that product archived on the internet.

From 2006, now long gone, you know where to look :-) <http://www.s100-manuals.com/CPM-BootDisks.htm>

Thank you very much for this most useful tip/hint! I appreciate your help.

WOW!!! Thanks Martin!! What a "gold mine"!! I designed and built a 68K SBC (68000 running at 18.4 MHz, 2MB SRAM, 1MB EPROM, compact flash interface via 8255, and 2 serial ports via 68681(38.4k baud)). Got some things working in CP/M-68k, but found
software to be a limiting factor. That archive has 3,000+ files --> endless fun!

I see that CB68 (BASIC compiler) is in the archive. I have copies of it on my SBC, but although it seems to work OK for simple things, anything more complex just generates "exception $03". Anybody find it useful? What am I doing wrong? The compile
works OK (no errors), and the link too -- "LINK68".

Mostly, I use a GCC cross compiler and run the resulting binaries on CP/M-68k using a little thing I wrote called RUN.68K. It just loads the raw binary, and makes it look like a generic executable that CP/M-68k seems to like. GCC generates very fast
code!

I can post a photo of the SBC if anybody is interested.

I'm collecting M68K material for a long time now.

Always hoping to find ssytem disks for a nice coprocessor card I got
in the late 1990s without any software or docs.

So nothing to learn from, everything had to be found out from the
ground by trial and error.

Its a definicon DSI-780 with 12MHz, see <http://www.spiess.ch/emme2/e2news/news02/node2.html>

The information found here helped me to get is running. <http://cini.classiccmp.org/pdf/byte/Definicon%2068020.pdf>

I can reset the processor and load a memory image to the card.

Oh, I really enjoyed your site!
68000, z80, firmwares, etc., everything the technical heart ever wants.
I'm glad to be of help now and then :-)

Exception 3 is an address error. As in the program attempted to fetch a word/long using an odd address. But you knew that...

Run using DDT to find out more.

I think, the CB68 files are somewhat corrupt :-(
The difference to the files below are missing 1AH bytes.

Try the ones from <http://www.cpm.z80.de/download/cb68.zip>

Thanks! Google pulled the rug out from under me when they switched over to a new format. IMO, the new format is pretty useless, and they froze the content on my original page when they did the switch, so I can't add to it. Since their freeze, I've
managed to build a 68020 SBC that runs at 20 MHz. It's a *real* kludge (for example it is hard-wired for an 8-bit data bus), but I discovered that the 68020 runs quite well that way (I originally thought that it would be "dog-slow"). It has 512k SRAM
and 64k EEPROM with 2 serial ports via a 68681. BUT, there is no on-board mass storage (such as a compact flash), so all I can do is download S-records to it and run them. The PCB is small (about 14 cm. x 12 cm.). I've been thinking about trying to
build a more full-featured version, but so far I've been reluctant (mostly because the size of the PCB would make it expen$ive!).

I'm glad to be of help now and then :-)

Much more than "now and then"!

I took a look at the Byte articles on the Definicon. Pretty complete schematics! I'd love to see the equations for the PALs/GALs. I hope you can get yours running!

I think you're 100% correct. Why would a compiler produce an addressing error? Aren't they supposed to catch things like that? Or at least flag it as an error during compile or link?

Try the ones from <http://www.cpm.z80.de/download/cb68.zip>

Yes, I want to do that. Something must be wrong with the files I have.

and I said:

I lied!! I can't see any way to do that on this thread.

Roger, I cannot reproduce your problem with David's emulator.

I used *both* the CB68.REL and CB68.L68 from <http://www.cpm.z80.de/download/cb68.zip>

I used the existing linker LINK68.68K in his "diskc.cpm.fs".
The good files are called cb68ok.68k and cb68ok.l68.

Hi Mogens --

The best archive for CP/M-68K stuff, and lots of Cromemco stuff as
well, is the old Maben site. Marcus moved it to GitHub, and made it
inaccessible unless you are granted permission. I find that getting
permission to the GitHub repository is a *real* challenge. Your
experience might vary?

From 2006, now long gone, you know where to look :-) <http://www.s100-manuals.com/CPM-BootDisks.htm>

See here for CP/M-68K on his MEX68KECB <http://davesrocketworks.com/electronics/cpm68/>

The simulator is here <http://davesrocketworks.com/electronics/cpm68/simulator.html>

I have only compiled the simulator under 32-bit Linux, 64-bit is
not very useful, if you want to run a lot of old utilities :-)

Doing everything under Slackware Linux since +20 years,
I can only really help you to get it running on Linux.

Can the simulator even run on any other OS?


If nothing else, you can at lest copy files out of the HD image
"diskc.cpm.fs" with "cpmtools".

I'm at this time a little bit overwhelmed, to describe everything from
start to end.

But I will try to help you over any difficulties when they arise.

The simulator is here <http://davesrocketworks.com/electronics/cpm68/simulator.html>

I have only compiled the simulator under 32-bit Linux, 64-bit is
not very useful, if you want to run a lot of old utilities :-)

Doing everything under Slackware Linux since +20 years,
I can only really help you to get it running on Linux.

Can the simulator even run on any other OS?

That would depend on the 68K sim used as a base: Musashi. Which has
turned out to be a bit of a moving target. I really hated it when the
source files were rearranged which broke existing code (like mine).

Console I/O might need a bit of work.

I think you're 100% correct. Why would a compiler produce an addressing error? Aren't they supposed to catch things like that? Or at least flag it as an error during compile or link?

Try the ones from <http://www.cpm.z80.de/download/cb68.zip>

Yes, I want to do that. Something must be wrong with the files I have.
and I said:

I can post a photo of the SBC if anybody is interested.

I lied!! I can't see any way to do that on this thread.

I had exactly the same Problem with CB68 (Exception $03) on my 68000 boards. (On my 68020/030/040/060 CP/M-68k boards there was no error).

After changing the memory region size in my CP/M Bios it worked fine.

Hi Martin,

So, how can I find the "ok" files? I've forgotten how to get to the "emulator".

Rereading your question, I finally understand ...

I have just renamed the files.
The "ok" files are the one from "cb68.zip".

The simulator is easy to build. Use the following version of musashi, which works well:
<http://caesar.logiqx.com/zips/libs/cpu/musashi/musashi331.zip>

Go into an empty subdirectory(!), extract both, but don't overwrite the "m68kconf.h" from cpmsim.zip.

"make"... and a few moments later, you have a running simulator :-)
Just did it, works well under Slackware 14.2 64-bit!

First results while trying to find the cause of oger's problems with CB68:

The http://www.cpm.z80.de/download/cb68.zip:
-rw-r--r-- 1 martin users 13824 Dec 18 1997 CB68.DOC
-rw-r--r-- 1 martin users 93312 Dec 18 1997 CB68.L68
-rw-r--r-- 1 martin users 213632 Dec 18 1997 CB68.REL

Comparing this with the trisoft archive
CPM-68K/Languages/Basic/CBASIC_68K_1.0:
-r--r--r-- 1 martin users 93311 Apr 27 2004 CB68.L68
-r--r--r-- 1 martin users 213629 Apr 27 2004 CB68.REL
-r--r--r-- 1 martin users 69120 Apr 27 2004 LINK68.REL

The odd filesizes were first alarm signals,
further examination shows, that every 01AH byte is missing
from the trisoft files.

So a first glance it seems the corruption at least follows
some regular schema.

The LINK68.REL looks truncated relative to all other files
of the same name elsewhere.

Looking around searching a comparable LINK68.REL I found
LINK68.68K in CPM-68K/Languages/Pascal/Pascal_MTP_Working:
-r--r--r-- 1 martin users 37631 Apr 27 2004 LINK68.68K

A good version of the file is in rlee peter's cp/m archive
rlee/D/DIGITAL RESEARCH/CPM68K/CO16-68K:
-rwxr-xr-x 1 martin users 37632 Apr 11 1999 LINK68.68K

Same form of curruption, one 01AH somewhere in the middle
is cut out.

Not good... :-(

Mostly, I use a GCC cross compiler and run the resulting binaries on CP/M-68k using a little thing I wrote called RUN.68K. It just loads the raw binary, and makes it look like a generic executable that CP/M-68k seems to like. GCC generates very fast

code!

Roger,

that sound very interesting !
What GCC cross compiler version are You using ?
How do You compile the program (compiler switches) ?
What does RUN.68K exactly ?
Can I have a copy of RUN.68K or RUN.S ?

Regards,

Josef

Looks like a dumb EOF mark (^Z, 0x1A) scrubber was used on binary files.

A smart one would look only in the final record. An even smarter one
would check for binary files first.


It should be possible, if tedious, to undo some of the damage.

Load the binary (this only works if it is executable) using DDT. Then
starting from the beginning, scan the code. Deletion of a byte should
cause significant weirdness in the following code. Insert a 0x1A in what
looks like the appropriate spot. Reload with DDT and repeat.

You would have to be pretty motivated.

And patient.

This was also my first idea.
Thanks for confirming that.

Or Create a simple automatic tool to quickly detect the first illegal
position in a binary. Then hand fix it directly or insert a dummy byte
and continue. At the end return to all the unclear points and retry.

The 68k has a word oriented architecture, a shift by one quickly leads
to illegal opcodes. But data areas will require some disassembly.

For plain binary files, this could work.

Is there somewhere a documentation of all the object formats
(standard or not?) used by the compilers?

Did we solved the CB68 issues? compile ASCII mandelbrot with CB68 under CP/M68K is part of my test suite. It all worked on my 68K designs from 68008 to 68030 so I think I have the working binaries of CB68.rel and library CB68.L68. I believe I

Hi Bill,

I think that the questions about CB68 came up because I was unable to compile "asciiart" with my version of CB68. I thought that perhaps my CB68 (or the library) was corrupt, but it turns out that it was a problem with my CBIOS attempting to set the
memory region with an odd number. I fixed it, and was able to compile OK.

As an aside:
CB68 version: 1:04 23k
XGCC version: :13 7k
also ran it with "COM2X" using Micro$lop MBASIC -- so slow I didn't even let it complete!!!
