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.

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).
