The problem is that while many of us have looked a: we can not find a KS-11 in real life (CSS did make that many), b: we can't even find documentation about it (Ken's surviving code is the best doc we have). FYI: go to bitsavers and download a copy of the PDP-11 Processor Handbook, but note the data. You probably will want (at least) both an early and a later one, as the later ones often dropped details about some of the models that were not being manufactured. For instance, I have a couple of different ones, and the '78 version really one talks about 04/34/45/55/60 - the previous processors like 03/15/40 are not included. So you need an early 70's version to include them, and later versions for the 44/90 etc. BTW: Page 4 of same, have a graphic showing the HW requirements for the DEC OS's. On the X-axis is the OS, the Y axis the model. RT-11, MUMPS-11, RSX-11M, RS-11S are the only OS's that were supported for the 04.

The question is can I run Unix on a PDP 11/04? I've dug around and it's unclear to me, = so I'm asking y'all.
