ICL PERQs

The NMOC certainly cannot be accused of dumbing-down: the entire description of these machines reads "First commercially-produced personal workstation - the PERQ CPU was a microcoded discrete logic design based around 74S181 bit-slice ALUs and an Am2910 microcode sequencer. It has 20-bit wide registers and a writable control store (WCS), allowing the microcode to be redefined. The CPU had a microinstruction cycle period of 170ns (5.88Mhz). PERQ 1 could be configured with 256kB, 1MB or 2MB of 64-bit-wide RAM."
