Guy’s FWIW, the data on 8” SD disks is not as labile as you might think. I have about 100 of them here from late 70’s to early 80’s. With only one exception (and that was a 1K DD disk) I have read about 30 with no problem (using a Versafloppy II or our ZFDC board). They were stored in the 8” plastic sealed boxes in a cool dry place but nothing special.

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.
