I have a PDP-11!

Posted <2017-08-04 Fri 16:04> by Aaron S. Jackson.

At long last, I have a PDP-11/73! It's not quite in my arms yet. It's still at bnl's house, since he kindly picked it up for me (Thank you!). It is in the BA11 chassis from a PDP-11/23 PLUS, but that does mean it has the 22 bit Q-bus backplane, and therefore can take the 11/73 processor.

Full specs:

The plan for this machine is fix up my RL02 drives and install ULTRIX-11 3.1 onto the two RL02K packs. It will be wonderful.

Here are some photos!

BA11 chassis, PDP-11/23+PLUS

M8192 CPU (11/73)

Two M8067-LA (512K Memory)

M7195 (2 async SLU, clock and an extra 128K of RAM)

M8061 (RL02 disk controller)

M7504 (DEQNA ethernet controller)

M7546 (TK50 tape controller)
