Subject: RE: CompuPro floppy controller differences
Ok, I got the CompuPro Disk 1 controller last night
and have a quick
question about configuring it. The card can handle both 8" and 5.25"
drives,
and the plan is to use a 5.25" 1.2mb PC drive as
a substitute for the 8"
drive (I only have access to 8" disk images).
Now, when I do this, do I leave the jumpers on the card configured for the
8" drive but use the 5.25" interface connector, or do I have to configure
the jumpers for a 5.25" drive? I'm thinking leave it for 8" except to the
extent that the jumper had to do with swapping signals on the drive
interface connector.
Thoughts?
Normally when replacing an 8" with a 5.25" HD, I would simply leave the
system configured for an 8" drive and make an adapter to connect the
5.25" drive to the 8" connector - I have not looked at this in detail,
however
as long as you can set jumpers to connect the right signals to the right
places on the 5.25" connector it should work. Just make sure the signals
are the same ones that would go the the 8" Drive (no extra conditioning
etc.)
