Thanks for doing this! I do have a few questions regarding emulator
software:
- You mention that the emulator combines "the SimH project structure"
with Wild Hare's commercial code. I take this to mean that the emulator
is an extension of simh to support the listed DG processors and
devices

Something quite similar, . . . (probably a hassle to switch over) I had a
KVM switch, that permitted two computers to share one keyboard mouse,
monitor, and speakers. DE15, two USB ports and a headphone jack (IOGear
GCS632U?) It apparently watched for a hotkey from the keyboard to
activate sw
Perhaps cheaper still, a Raspberry Pico. Those go for $4, which even for the
smaller Arduinos is hard to beat.

I suspect that a cheap minimal MCU could not only do the job, but do it
by scavenging power from the RS232 signal lines (like old serial mice
did). It's really surprising how miserly these things can be with power
requirements nowadays.

Black box may have something. They had something similar where you could call
in via phone and activate a switch to reboot a computer.

Thanks to everyone who responded. And thanks to Wayne for the black box
suggestion. I have actually been thinking about that very product. What it does
is switch a master port to one of several other ports. Not far from what I'm
seeking. I was thinking of buying one of these and hacking it to tr

Probably overkill. I think it could be done with an arduino.

If they do it probably costs about $500. Blackbox is not the company
they used to be. (From someone who still h
