Re: [N8VEM-S100:673] CP/M-68 on the ECB mini-M68k CPU board

8" media generally holds up pretty well so I'm hopeful that most or all of this data can be saved (I tend toward foolish optimism - that's why I collect vintage gear :>) ). Things are buried under a few layers of honey-do projects but I'll try to get something going in the next week or two and pass it along.

I'm impressed if you have 8" disk drives that still work.  Somehow, somehow, I hope you can recover the data on those source disks.  BTW:  I am cross-compiling with GCC.  I hate the GAS syntax for assembly code, but the GCC-generated code is second to none.

I have not posted source code or listings yet, as there are still a few pieces needed to make a palatable distro.  I am keeping Mike Sharkey up to date with the source backups; and I would be glad to send the zip files to you for the asking.

John (and other 68K fans),

I've located a bunch of old CP/M-68K stuff recently, including CP/M-68K v 1.3,
FORTH and 68K tiny BASIC. Is there a central listing of the software you already
have? Almost everything is on 8" disk which I should be able to read but I don't
have a system set up currently.

Hopefully, moving to the S100 68K board should be pretty easy from here.

Great work!
