The DECUS NOP SIG is dedicated to the retention, restoration and running of Nostalgic Obsolete Products. (NOP's).
The poster shows three generations of the PDP-11.
On the right are two of the original PDP-11/20 computers mounted in the same cabinet. The PDP-11/20 was released in 1970. These units were used by the CSIRO to control an X-RAY diffractometer. In front is an ASR-33 teletype.
In the middle is the PDP-11E10 of 1973 vintage. This was the first "packaged" system ever sold by Digital. It comprised a PDP-11/10 central processor with 16,192 words of core memory, bootstrap, 2.4 Megabyte cartridge disk, dual magnetic cassettes and LA30 DECwriter console, all installed in a 6 foot cabinet.
This unit also had the LPS laboratory peripheral unit. The package configuration saved 25% over the sum of the parts. It was installed at the Preston Institute of Technoloy in 1974.
On the left is the top of the line PDP-11/70 of 1975 with console and expander cabinet. This PDP-11/70 was the first RSTS/E machine installed in-house by Digital Australia - the famous node SNOE01.
These units are on display in DEC's Australian Museum.
No. 3 in a series.
