Jerome Fine replies:

Unfortunately, my personal experience with a PDP-11/73
is that a complete system is now less expensive than the
repairs that you mention. If you know the part numbers
for the individual boards, then popular ones might be
easy to replace. But I have found that a complete system
comes along every so often - usually at a reasonable price
if you are patient. If this was a BA23 box, then it should
not be too difficult to find another one in the US.

A dropped disk drive usually has problems.

On the other hand, UPS does NOT have a good reputation
of being responsible for damage of any sort. Was the shipment
even insured? And for how much? Reply off the list if you
want to keep that part private!

Sincerely yours,

Jerome Fine
