The following is from a PDP11/Mass Spec customer of mine. If anyone has any
ideas for him feel free to contact either of us. I will just forward
anything to him if it gets posted to me or the list.
With a little direction he can run diagnostics and has available an
electronics shop and decent test equipment like scopes. I don't know if
they have things like logic analyzers however. ( I did not need one the one
time I was on site)
It even meets the 10 year rule.:)

----------------
We have an X-32 computer (CPU/3), a German unix machine from 1989. This
computer operates a Bruker AMX-500 NMR spectrometer. The computer is
functional except that Fourier transform calculations frequently give a
massive "transmitter" spike that is NOT hardware related. Although we
normally do all repairs through Bruker, the director of our facility does
not want to repair this problem because the computer will be replaced
within a year and the instrument is functional. However, for a frequent
user (me), this problem is extremely frustrating and time-consuming. The
problem is almost certainly one of the three following X-32 boards:
CPU board H2297 ECL 12
Memory 16MB H2271 ECL 02
Array Processor H2231 ECL 06
If anyone can help with this problem, please contact me by email.
Thank you.
