PDP-6
PDP-6, (Programmed Data Processor-6)
DEC's first 36-bit [5] personal mainframe computer developed and manufactured from 1963, and shipped since 1964 [6], influential for the later PDP-10 with almost identical instruction sets. Addressing remained 18-bit, as in earlier DEC machines, allowing for a 256 Kiword main magnetic core memory, optionally with 16 words of fast memory constructed from discrete transistor flip-flops [7]. Output could be displayed on a DEC 340 display [8] [9] [10] [11] [12].
Already supporting Time-sharing, the operating system used was an early version of what later became TOPS-10, and several sites made custom versions of the system, available as source code. The PDP-6 with serial number 2 was donated to MIT's [13] Project MAC, where it was used to develop the ITS operating system. Richard Greenblatt et al. developed the Mac Hack VI chess program entirely in MIDAS, the PDP-6 macro assembler.
