A look at the CPU card from a PDP 11 / 24. DEC part # M7133. A nicely representative board design from the late 1970's.
Saved for later - I once restored something similar, an 11/23. The boards all checked out, it came from an industrial environment and every card edge and connector needed a good solid cleaning, and I was amazed when it fired up. Neat machine to work with, half because of what it was and half because of what it controlled - a big Brown & Sharpe coordinate measuring machine. Actually got to use the FORTRAN I learned in HS and college.
Thanks for that. My computer science classes in the mid-80's were mostly using a PDP-11... I couldn't tell you which model. This was during my university days in NB, Canada.
I never actually saw the computer itself, let alone its internals, so found this interesting. My interactions were all from either a CRT or teletype terminal.
