Can anyone help me with settings on this drive?
Specifically, drive select, termination, and pinouts on the power connector
(J2) would help.
Drive select - a choice of 1/2/3 - is determined by the programmable
shunt at location 1F. Installing a DIP switch is a much handier means
of selection. Configured for multiple drive installation, MX should be
open, HS shorted, and only the desired DSx shorted.
Termination is by a 150Ohm resistor DIP.
The power connector is the same as used on more modern 5.25" floppy
drives with pin-1 at 12VDC, pin-2 12V return, pin-3 5V return, and pin-4
5VDC. Pin one is identified on the component side of the PCB.
Also, the specimen I have has a power switch on the
front which appears to
be factory-installed. Is this common for this drive? The photos I found
on the 'net don't have a switch . . .
Sounds like a skillful add-on.

If I am not for myself, who will be for me?
And if not now, when?
