Dear list, I'm currently restoring a PDP-11/70
system and need the
following boards to complete the CPU:
FP11-C slots:
M8127
M8128
M8129
Cache slots:
M8142
M8143
M8144
M8145
Any help finding these is appreciated. Thanks.
So, it turns out that I *do* have an FP11-C. My PDP-11/45 with the
KB11-D processor in it has an FP11-C. So, at the least, I would need to
try and figure out if the boards in it right now are the ones that came
with it [This is what my notes from 1989/1990 say], or are my spares,
and, at the least one of the two M8126 boards is marked "Bad".

I think the FP11 boards are not essential for the 11/70
They only add hardware FP support.
However, I think that the cache boards are essential.
Not sure the 11/70 will work without them.
