Some time ago, Greg Christie, then at Apple, booted up a 3B2 with a 5620
attached and invited me to play with it. Now _that_ was a trip down memory
lane. (The 3B2, maybe not so much.)
It was a reward for an interview with him, recorded on video, about the
early days of 2d graphics as I saw them, for a course for employees. But
being Apple, even though it was 0% proprietary, it will never see the light
of day.

This looks like some really nice work. I used a BLIT
at UW Madison
and loved it, it was way more useful than a terminal and way less
fuss than a full blown windowing system. Felt like the knee of the
curve. All of that over a serial line, that's impressive.
I dunno, but I bet that Rob trys it out just for a trip down memory
lane.

Hello all,
I've recently been improving the AT&T/Teletype DMD 5620 simulator I
wrote
a few years ago. It can now run either the 8;7;3 or 8;7;5 firmware.
It also now supports executing a local shell or connecting directly to a
physical or virtual tty device. It runs natively on Linux or macOS with X11
or Wayland, but I would love help creating a Windows version if you're a
Windows programmer (I am an occasional Windows user, but I am not at all
knowledgeable about Windows programming).
Full details are available here:

The source code is here: https://github.com/sethm/dmd_gtk
Many thanks go to my friend Sark (@crtdude on Twitter) for tracking down
the 8;7;3
firmware and dumping it for me. I'd also like to thank Mike
Haertel for helping find bugs, providing feedback, and inspiring me to get
it working with Research Unix in addition to SVR3.
Feedback, bug reports, and pull requests are all welcome!
-Seth
