Revision as of 15:56, 5 February 2024

The configuration of the various Incompatible Timesharing System‎‎ time-sharing PDP-10 mainframes at MIT (in the AI Lab, where it was born, and in LCS, only other organization to run it 'in production') are given here. They were all physically in Technology Square.

AI PDP-6

DM PDP-6

AI KA10

The AI machine was the first KA10 at MIT. It was initially installed as a 'slave' processor to the AI PDP-6 in a tightly-coupled multi-processor; later the two machines swapped roles. It was the first KA10 there to support virtual memory (an MIT custom modification).

DM KA10

Another KA10, with a Systems Concepts DM-10 paging box, and also:

ML KA10

Another KA10 with a DM-10, and also:

  • 4 x 128KW MD10's
  • RP10
    • 4? x RP03's
    • 4 x Calcomp
  • Its DF10
  • TM10A
  • 1822 interface
  • eventually, a CH10

MC KL10

The CPU was a stock Model A; it ran custom microcode, though, to implement the 'MIT paging box'. The main memory and channels were also 100% stock. Also:

  • 8 x MF10's (originally); later upgraded to MH10's.
  • (later) An Ampex ARM10L 'external' memory box
  • An RH10
  • Its DF10
  • TM10B
    • Some sort of high-end DEC magtape drive
  • Its DF10
  • A DTE20
  • A DL10
    • Another PDP-11/40, the 'IO-11'
      • A DH11
      • Later, a Trident controller
        • Initially one, eventually three Trident T-300 drives
      • Eventually a CH11
  • 'KL-UDGE' LH 1822 interface (maybe a clock, too)

AI KS10

The KS10's were all pretty stock, hardware-wise; they also ran custom microcode. Also:

MC KS10

No tape drive; backups must have been done over the Chaosnet.

  • Disk RH11
    • RP06
  • LH-DH/11
  • CH11
  • DZ11

ML KS10

  • Disk RH11
    • RP06
  • CH11
  • 4 x DZ11

MD KS10

  • Disk RH11
  • CH11
  • 4 x DZ11
