Domingo da Dave-entrevista: David Plummer entrevista David Cutler - Retrópolis
3 horas, 10 minutos e 27 segundos de David Plummer entrevistando ninguém mais ninguém menos que David Cutler - que, para quem anda com a memória fraca, é o pai do RSXm, do VMS, do Windows NT (e portanto de todo o Windows como o conhecemos hoje em dia) e de sei lá mais o
Stephen Hoffman@dosnostalgic VAX/VMS circa 1978 used to boot with PDP-11 RSX-11M compatibility mode available and a fair chunk of the apps in the early VAX/VMS versions were RSX-11M apps running in compatibility mode.
The VAX-11 boxes supported PDP-11 instructions in hardware.
You could run your existing PDP-11 RSX-11M apps directly, too.
That all ended at VAX/VMS V4.0 (~1984), and with then-new VAX models after VAX 8600.
VAX 8600 was originally to be named VAX-11/790, but marketing marketed and dropped the -11 with the “architecture for the ‘80s”.
PDP-11 RSX-11M compatibility mode became a separate product, and the PDP-11 instructions were emulated, and the -11 was dropped from VAX.
Technically, an LSI-11 console processor booted RT-11 from the 8” console floppy which then booted the VAX-11/780 (organizationally within he hardware, the VAX was an enormous LSI-11 peripheral) which ran VAX and PDP-11 instructions and which could run simh emulator to emulate PDP-11 running RT-11. If the LSI-11 failed—as happened on a couple of occasions—the VAX could continue to run. Just not reboot.
The approach Apple used for migrations with Rosetta and Rosetta 2 was far smoother.
Yeah. Fun times. When it all worked.
There are shenanigans in newer boxes too, but they’re usually somewhat better hidden.

Peter Whisker 🇪🇺🇮🇪 aul segotia@markmoxon I worked on the BBC Teletext systems including the upgrade from 2 VITS lines to 4 back in the 1980s. A colleague designed a new encoder board which was a great improvement. It connected to a #pdp11 DR-11W parallel interface. The software was written in RTL/2 and MACRO-11 under #RSX11M on a PDP-11/34
eiZenLater, the "Brisbane computer based #totalisator" was running on a #PDP11 running #RSX11M in two mobile vans/trailers, each one hosting a twin PDP11 running in hot standby mode.
