Apart from "no because it's not open source" there is also "no, because DEC didn't use source control like that". Late in the RSTS development there was a very primitive source control system that understood the notion of checking out a file in the sense of reserving it. But that tool (known

Re: [Simh] Various

Also not survived... We had an NCR Elliott 4130, but when the CS degree started, the students (four in the initial year) had a PDP-11 for various things. One of the staff wrote an assembler AND a simulator to run on the 4130, to reduce the need fro the real machine. It obviously helped with

Re: [Simh] Various

Did DEC actually sell that many? In my years of working around DEC gear starting in the late 1960s, I think I saw a card read/punch only once on a PDP-6 IIRC, but it might have been a KA10. I don't think I ever saw one on a PDP-8/11 or Vaxen. I used cards primarily with IBM, Univac, and CDC

Re: [Simh] Various

Our VAX 11/780 had a card reader in the very early 1980s for reading in the names and details of incoming freshmen so their accounts could be set up. It usually required a few runs to obtain an uncorrupted read of the card deck. The IBM system that generated the cards was on the other side of a

Any good simulation would have to include the semi-real I/O instructions RCC (Read and Chew Card) and DPD (Drop and Pie Deck). I'm with you about never again struggling to remove a card from the read gate that had been converted to a mini-accordion or measuring the size of a progrram in boxes,
