I now have a working Imsai now need to try to get the 8" Imsai floppy sub system working. I have a number of floppy disk controller but no Imsai FD controller. I have Cromemco 4fdc, Cromemco 64fdcCromemco 16fdc, dual systems FDC and some CCS fdc. I'm not sure of the cable connection from the Imsai disk to the controllers. I had heard the Caldisk pin out is not the same as the Shugart I do have CP/M working on another 64k Imsai using the CCS controller for 8" shugart and a Northstar controller for 5 1/4". Has anyone gotten the old Imsai drive working using CP/M? Thanks.
