This is FANTASTIC. It brings back many memories as I worked on both PDP-8s and PDP-11. On the PDP-11 I wrote device drivers for RSX-11M. Now for those of you that were not part of the DEC family back in the '80s, yes that is a long time ago, this probably all sounds like gibberish. It was a great time and in it heyday DEC (Digital Equipment Corporation) was a great company to work for.
I then moved to work on VAX/VMS systems which is where the DrVax comes from. I was still an operating system internals kind of guy managing a team of folks that wrote custom data communications device drivers for VMS systems.
It’s still amazing to think you can replace the power & functionality of computers from the 70s & 80s with something like the Raspberry; not entirely or exactly of course, but still…
