Re: [Simh] Various

1. I can confirm that RT11 V5.3 INIT does not work properly with an RL02 in 3.10. My next step is to trace back changes, because I think it used to work. 2. There's no card reader for the SDS 940 because a) I hate card readers (from having used them way back when) b) I thought there wouldn't

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

[Simh] Card Readers on PDP-11's

Coming from an IBM 1130 to a PDP-11/20 we had 12kb of core memory, dual RK03's, replaced with RK05's, paper tape reader, paper tape punch, card reader, teletype, printer and plotter. At the time we were running DOS. We had several IBM 029 card punches. There were no online terminals. We

Re: [Simh] Of DEC and cards

I don't have numbers, but I do have experience.  I ran into quite a few card readers on DEC gear - fewer (but some) punches. 8s, 11s, 10s, 20s, and VAX - they were gone by alpha. The card readers were most often specified for migrations - people who had a business process, or even just software

[Simh] RT11 sources needed

Okay. If I'm going to trace this RK11 FORMAT bug and RL02 init bug, I need sources (with comments) for some version of RT11 that supports those devices, like V5.3 or later. Both are probably in DUP, but I'd need to trace driver code too. Over the years, I've managed to stockpile sources for

Yes, and until ~ the 1442, the IBM readers used a row of metal brushes to read the cards (they'd go through the holes and contact a metal plate on the bottom).  All the early IBM gear was mechanically interesting - I suppose from their origins.  Springs, brushes, cams, levers, solenoids,

In the TOPS-10 world, ANF-10 RJE stations could have card readers and printers.  The TOPS-10/20 DN200 also. But most "RJE" station software on the DEC side made the foreign mainframe look like a batch queue, and you would submit a file to that queue.  The software (typically DEC 2780/3780
