All of them are for various hard drives.  None floppy of any sort. The first 4, 2840, 34, 21, and 09 all look like ones I'd use on a Western Dynex either 5mb or 10mb (capacity) drive.  100tpi or 200tpi. The others are progressively higher density, someone else may recognize them.  Epay periodically has some guy listing them for high prices, and though I'd never pay what he wants if you can find his listings, they might be a good reference if noone else here turns up with an answer. From the ages of the guys I knew in the 70s and 80s that serviced these, and their disposition of working on the hardware, they're probably all mid 70s, and not paying much attention to this sort of thing anymore.  They certainly knew the subject well, the ones I knew. A fellow I knew ran AHMCO  (After Hours Maintenance, Company), which was well named, as when does this crap fail.  anyway, hopefully someone has either memory or knowledge of these. I've got a few sets for my older Microdata Marathons, and Dynex drives in similar packaging. On a side note from my experience, wish more companies had used the pink plastic for bagging boards, and this foam, as I've not seen any of it broken down like many types of foam.  And I'm talking about Los Angeles air, which kills anything plastic with ozone. thanks Jim On 5/30/23 20:57, devin davison via cctalk wrote:

I don't normally beg for help, but I'm going to beg for help, because this would be really useful if I could get it to work. This guy: TURBO PASCAL (mark-ogden.uk) <https://mark-ogden.uk/mirrors/www.cirsovius.de/CPM/Projekte/Disassembler/TURBO/command/TURBOcommand-en.html> Has posted .MAC files that supposedly build a command line version of Turbo Pascal that lacks the editor, which would be really nice as I use RunCPM and an external editor to work on Turbo Pascal 3 for CP/M I've tried building and linking this with M80 and L80, and it doesn't seem to work. I really don't remember what I'm doing with these tools, which I haven't used for 30 years. More probably. I'm not sure if the author is even still alive, and I have no contact details for him...as this is a mirror of an old page. Anyone got any ideas? I'll buy you a beer if you meet me someplace in England. Thanks, Mark (aka John)

I was trying to assemble it under RunCPM, but for some reason, it didn't like that. When I did under z80pack, it worked just fine. Well, kind of fine. The guy who did this seems to have patched it to like running on an Amstrad CPC, so if you use GotoXY it doesn't work. I just wrote my own...
