Unibus, Uniprobe and Unibone tales
As my PDP-11 came without peripherals I need something to make it come alive..
Unibus information
There are multiple parts inside an Unibus:
- UNIBUS Slots are the real Unibus
- SPC are slots usually reserved for peripheral cards?
In addition, there are two versions of Unibus. Normal Unibus and modified Unibus. These are not compatible! In “newer” PDP-11’s both of these are present on the backplane, and it is a bad idea to use boards meant for the one in the other.
Picture from here, where there is also way more information.
To test the Unibone we need it in a terminated backplane like the DD11-CK:
We need two passive terminators (M930, donated by Geert):
Login to the Unibone with:
ssh root@ip
password: root
