PDP-11 Unix V7M-11 V1.0 under SIMH

2021-10-02 Thread Tony Nicholson via cctalk
Recently Al Kossow made available a zip file containing a Micro/PDP-11 installation kit for Unix V7M-11 V1.0 on bitsavers as RX50 disk images. Tinkering away here in Covid lockdown, I've managed to get this running under SIMH pdp11 emulating an almost historically accurate PDP-11/23 plus. I've pl

*Neat*! I was thinking of trying to lay this down on a real 11/23+ here at the house, then realized I didn't have two RD51's. Can it gen on an RD53 by chance, I could upload one of those to a disk in a weekend or immediately with the Dave Gesswin emulator (which I need to return but we're just

I doubt you'll be able to use anything other than a RD51 drive - as this ancient V7M doesn't yet support newer drive types.  You might be able to put some of the system files on an RL02 - but I haven't confirmed there's a RL02 boot loader on this kit. Interesting. Given that it's MSCP it should

I wonder if it supports at least an RD51, since those arrived together with the RD50. Yes, it did. Venix 1.0 ran on a RD51 and was a LOT faster. I keep the RD50 around mostly as a "good god, is this faster than a floppy" conversation piece. Chances are it would be noticeably faster with an
