As has been pointed out, someone is most likely after the 3 RD54's. The
thing to remember is that there are still systems being used commercially,
or by the Government that use these drives. The cost of qualifying
different hardware to move to SCSI far outweighs the cost of obtaining
RD54's.
Anyone have any
ideas as to why most BA123s are missing the door that
covers the operator's panel? Is it just easily broken and lost?
I think they were shipped broken. You had to be very careful using
that door, or the pegs (hinges) would break off. Since all the intresting
buttons were under the door, it needed to be opened fairly frequently.

I had one that was intact. The top peg that holds it in place and makes
up the hinge is now broken. I'm still ticked off at my Mother over that
one. I had the panel off, and she knocked it over on a hardwood floor.
The result, the peg broke off. :^( That was a few years ago, I've still
got the peg, and one of these years I'll try and patch it.
I recently fixed a few cracks in the plastic trim on my BA123. It seems to
be made of ABS, but I'm not 100% sure. In any case, Methylene Chloride
certainly did the trick, and the plastic trim on my BA123 looks quite nice
now. Of course, the door for the operator's panel is missing, but I guess
that is quite common ;)
Anyone have an extra drive control panel for the front operators' panel?
My BA123 is missing one, and I'd like to replace it. I know some complete
front panels have come up on the list in the past, so maybe they are still
floating around in parts boxes.

I suspect what you really mean is that they use the ST-412/506
interface, but as a matter of fact they RLL very nicely given the proper
controller.

I repaired a post for mounting a power supply in an IBM Model 80 with JB
Weld. It was a tall piece of fiberous plastic that didn't really lend
itself to be "glued", but the JB Weld seemed to work very well. I still
have it, but haven't open up the machine recently to see if it's still
holding, but I would assume that it is.
