Which model 68020 Cromemco is it? I might be able to
find a spare 64FDC...

Long shot, but if you have another or Josh doesn't take it I'd love to give
it a home. I have a complete Cromemco board set here in an IMS-5000 chassis
and a pair of TM848's but have consistently failed to get the 16-FDC to talk
to them reliably. I'd dearly love to get a 64-FDC for it to go with the ZPU
and/or an STD hard disk controller (or an IMI drive to go with the WDI-II
controller I have). Anyone?
FYI the ROM on the 'FDC flips in and out the entire top 32K bank. During
boot RDOS ensures that the top 32K flips in and RDOS then flips out giving a
clean 64K map. All done through port 40H.

Hi Jim,
Are you the same Jim I'm corresponding with elsewhere about a broken
256/1024KZ?
If so, you and I can discuss the 64FDC off-list; I haven't heard from Jerry.
I do have some IMI drives, both the 8" 11MB and the 5" 5MB and 20MB units,
but I'm pretty sure at least some of them are non-functional.What
size/capacity are you looking for?
IMI drives were also used by Corvus; as a matter of fact the two companies
ultimately merged. The IMI 20MB mechanism was also available with a normal
ST412/506 interface card and used in XT clones etc., in case you have a
defective drive with a good IMI board and can find one of those drives.
