Re: [Simh] PDP-15/76

I believe XVM/RSX supports it as well (although it is dependent on XVM/DOS for booting so the UC15 simulation will have to be working with XVM/DOS first). Not sure whether the distribution that's available includes enough to support it (since SIMH didn't support it I didn't look at that part too

Re: [Simh] The lost disk of the PDP-15

I suspect this might also be to the limited number of XVM15 systems that were actually sold. I used one at Syracuse University in the early 80's. We had the PDP11 and it talked to the RK05 disk drive. I was told that there was only about 20 XVM systems sold. We did not have any RP drives on the

[Simh] The lost disk of the PDP-15

While I was digging deeper and deeper into the extent PDP-15 sources, I found a tantalizing reference: "the RP03 is supported as an RP02." This was the first time I'd seen any indication that the PDP-15's RP controller supported the later, double-sized disk. The XVM/MUMPS sources (which are,

Re: [Simh] PDP-15/76

We have a bunch of documents related to PDP-15 and XVM/DOS. Some of them does not appear to be present on bitsavers. If there are interest we will try to make an effort and have them scanned. http://www.datormuseum.se/documentation-software/pdp-15-documentation The documentation was the only

[Simh] PDP-15/76

I've pulled together the hardware pieces for the PDP-15/76 (PDP-15 with UC15 PDP-11 IO processor), so now it's time to consider what software can be run. The most likely candidate is XVM/DOS-15. While vanilla DOS-15 had UC15 support at some point, neither a complete source kit nor the
