It is good that you have volunteered information that perhaps someone on
the list is dying to have. Perhaps a directory of people with maintenance
prints is needed? I would be willing to share information. Currently, I
have maintenance info on:

DEC PDP-8/e,f,m,s
Heathkits (various, I would have to look)
Interdata model 4 and 14
Sphere 6800
SWTPC 6800

Of course some of this stuff is stored away and may take an excavation to
find, but I am willing to make limitted copies.

Of course, I am looking for maintenance info as well:

HP 2100A
SGI Iris 2500T

Yes, it seems that EPROMs are robbed out of many otherwise nice machines.
A certain SGI Iris 2500T has just about EVERY ROM and big (PGA) chip
pulled out...

But it is still fun.
