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

Thanks Bob. I think it was Paul who suggested that formatting continues until an error for non-existing cylinder is returned. You proved that it is indeed designed that way. Thanks all for the clarifications, never too old to learn  Henk Van: Bob Supnik Verzonden:

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
