USB HxC Emulation working for Cromemco 5.25 and 8 inch

Post by __m »

The great news for me is that I now have USB HxC floppy emulation working for Cromemco computers both 5.25 and 8 inch

First I learnt that the USB HxC is only read only

Then I found that all the debugging (trying to get read/write working) had resulted in a critical wire coming loose.

There is the hardware mod that ties the READY line of the 2 different parts 5.25" and 8" of the controller together so that you then need only
use the 34 pin J2 connector of the Cromemco 64 FDC Disk Controller for all emulated drives

I also found that the documentation on the READY modification was unclear so that and articles relating to HxC and 8" conversion are now updated also here

Last Words
The Cromemco repository of documentation and disk images including .HFE HxC format is now stored in a Github and access is via first joining the Cromemco Google group, asking for Gihub access and then accepting the conditions.
