One has to realize that all complex chips are done in Verilog or VHDL. Many old
designs in processors can be re-implemented from timing and bus diagrams.
This is no longer possible with todays processors like Intel or AMD processors.

Those were mostly toys to amuse the CEs, like the baseball game BAT.
Chess 3.0 was implemented on Northwestern's machine and probably was the

The RICM just picked up a PDP-11/40 chassis that was modified to accept a
PDP-11/23 board set. It also contains a custom board to interface the
PDP-11/23 to the original PDP-11/40 front panel. It is quite an
