Rick,
From what
I've been able to tell, these boards can be used for
diagnosing things at the
microcode level on (at least) the first
generation microcoded Unibus PDP 11's (11/35, 11/45, 11/05) as well as
diagnosis of the RK11 disk controllers (with an appropriate plastic
overlay for the indicator lights). The question I have is can this be
used on an 11/34a to step through the microcode?
I'm not an expert on either the KM11 or the /34a, though I too have a
working /34a. AFAIK, the KM11 is not compatible with the /34a. However,
in addition to the processors mentioned above, I believe the /70 can take
advantage of two (one for the CPU, one for the FP11?), and the RK05 can
take one [both of which I also have]. Fairly certain there are a good
number of other peripherals that can use the KM as well.
Wish I could come across a pair. Someday when I'm wealthy I'll buy the
kit from Guy.
