Does anyone have an Altos CPM/MPM machine available?

[Bob Shannon]

I'm going to try to get my old Altos 5-15D working.

Currently its having a problem during power-on self test, drive B does not 
seem to
be seeking to track 00.  The machine will not boot from A: without thinking 
the B:
drive is happy.

The drives are CDC 720K 5.25 inch, full height drives.

I'm looking for spare drives, a parts machine, or a working Altos.
