All: Ok, I think I have all the pieces together that I need to get a new 5.25" floppy system up and running on my IMSAI: a Versafloppy (1771-based) controller and a suitable 5.25" drive and related cabling. What I need now is a CP/M disk image for the Versafloppy. Does anyone have a bootable disk image suitable for this board and a Z80 processor? Thanks again!
