Dear All,
Get ready to use 3.5 inch diskette drives instead of those big and
noisy 8 inch drives on your Cromemco (and therefore any other CPM)
genre computers:

(Note that this requires trivial modification of your disk controller,
in my case the Cromemco 64FDC to connect the 8 inch disk drive ready
of pin 22 to the 5 inch ready line which is pin 34. There is a link
in my article to a previous post showing how that was done already).
Regards marcus.
This is not generally hard to do, I've done this using, Compupro
DISK1A, CCS 2242 and a few others plus my own design that were
set up for 5.25" drives (designed before 3.5"). Even My KAypros have
this as they are lighter and can store as much or more than 80track
two sided doubled density 5.25" drives and three 3.5" can fit where
two half height 5.25 were. The latter being useful for packaged
systems that are cramped for disk space.
The usual problem is if the system was setup for the most common 8"
formats it will not always work for 3.5" without some mods to the
BIOS.
Makes a good improvement if you can at least take advantage
of the drives capabilities.
