Same here, I have a number of 8-inch floppies
(>40) with various stuff on them, CP/M 1.4, 2.0, games
Etc. They are all SSSD – I bought a fair number of
“used†8-inch floppies from eBay – they had been used
once for a backup in the early 80s then never touched since.
I have only had one disk fail, it refused to format and
quickly started going
“shhhhhh…shhhhhhhhh…shhhhhhhhhhh†when spinning. I
assume something got caught in the sleeve so I trashed it.
The floppies have continued to work for me for. When I wrote
the “driver†for CP/M 1.4 for my IAudio Video Card I
used Teraterm to connect to the system, all compiling and
testing was done on 8-inch floppies, it worked great and was
very much like how it was done back in the day.

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.
Great work!
