Diode ROM Book
A home-made 1-Kilo-Bit ROM is presented, made as pluggable diode matrix.
It can be interfaced to DEC PDP-11s via UNIBUS or QBUS interface.
You can set own memory content by bit jumpers, and execute code from it.
Why? Because a retro-nerd should've soldered a big diode array once in his life time!
How was it working on your machine?
