The above publications actually apply to several PDP-11 models:
|
|
|
|
- PDP-11/10, which provided a minimum of 128 words of read/write memory (and 1024 words of read-only memory)
|
|
- PDP-11/20, which provided a minimum of 4,096 words of read-write memory
|
|
|
|
The 1971 Handbook also covers some additional models, which DEC says were "functionally identical":
|
|
|
|
- PDP-11/15 OEM Computer
|
|
- PDP-11R20 Rugged Computer
