Title: PDP 11/24 CPU Card Teardown
Post by: electronupdate on March 13, 2018, 04:26:07 am
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.
