The DECUS NOP SIG is dedicated to the retention, restoration and running of Nostalgic Obsolete Products. (NOP's).Twenty one years of Unix* software is represented here, between the PDP-7 of 1967 and the VAXstation 2000 of 1988.
The PDP-7 was the original computer on which Ritchie and Thompson wrote the UNIX* operating system at Bell Labs in 1967.
The VAXstation 2000 sitting on teh butterfly table of teh PDP-7 is running the Ultrix operating system. It is showing 12 windows simultaneously.
This PDP-7, serial No. 60, was the third DEC computer to enter Australia. It was installed at the Australian Atomic Energy Commission, Lucas Heights, on 27 January, 1966 and run for 14 years, clocking up 111,577 hours.
The PDP-7 was an eighteen bit machine with a cycle time of 1.75 microseconds. It was notable for the solidity of its construction and for its weight-just over a half a ton!
It sold with 4096 words of memory and a teletype for $45,000. The VAXstation 2000 has 500 times the memory and sells for one quarter of that price.
This PDP-7 is on display in DEC's Australian Museum.
No. 2 in a series.
