PDPjs development relied on the following PDP-11/20 publications:
|
|
|
|
- [PDP-11/20 Handbook (1969)](http://archive.pcjs.org/pubs/dec/pdp11/1120/PDP1120_Handbook_1969.pdf) [[Original PDF](http://research.microsoft.com/en-us/um/people/gbell/Digital/PDP%2011%20Handbook%201969.pdf)]
|
|
- [PDP-11/20 Handbook (1971)](http://archive.pcjs.org/pubs/dec/pdp11/1120/PDP1120_Handbook_1971.pdf) [[Original PDF](http://bitsavers.trailing-edge.com/pdf/dec/pdp11/handbooks/PDP1120_Handbook_1972.pdf)]
|
|
|
|
The above publications actually applied to several PDP-11 models:
|
|
|
|
- PDP-11/10 (with a minimum of 128 words of read/write memory and 1024 words of read-only memory)
|
|
- PDP-11/20 (with a minimum of 4,096 words of read-write memory)
|
|
|
|
The 1971 Handbook also covered some additional models, which DEC says were "functionally identical":
|
|
|
|
- PDP-11/15 OEM Computer
|
|
- PDP-11R20 Rugged Computer
