Jerome Fine replies:

Are you sure you know what the I/O distribution looks like
on a BA23? If you don't, it can be described.

I would not undertake to split a 50 pin cable into what the
RD5n drives require. But I might have a spare. Let me know
if you definitely need one.

The I/O distribution panel sits just behind the drive bays. It is
accessible - as far as the cables are concerned for the drives -
from the drive bays. Since the BA23 has 2 * 5 1/4" full height
(old style full height - not PC full height), you can use an RX50
(actually two 5 1/4" floppy drives) and an RD5n drive.

If you should happen to have a 6 button front panel (probably rare),
then you can use two RD5n drives. BUT, BE VERY careful in
setting up the jumpers for DS3 and DS4. If you make them the
same (both DS3), pe prepared to lose all data on BOTH drives.

Sincerely yours,

Jerome Fine
