Very cool!!! Looking forward to playing with it.

I may be wrong but I thought there was a version of 'pi' for debugging
code running on the Blit/Jerq. Does that run in the emulator?

Hello Noel,
I'm actually not familiar with 'pi'. Thomas Cargill described a debugger called 'joff' that targed the MC68000 Blit in a 1985 paper titled "Implementation of the Blit Debugger", but as for the 5620, I'm not sure what existed.
I will have a look through the TUHS archives to see if there's anything in the V10 dumps, perhaps.

This is pretty cool. Can you post links for this and the 3B2 emulator?
I had one for a few years at Georgia Tech and I *loved* the keyboard.
It was a huge productivity boost being able to have multiple windows.
We used them connected to our Vax 11/780 with 4 Meg of memory running
4.[12] BSD (don't remember which) and having multiple DMD 5620s
with multiple windows open on each drove the poor vax to its knees...

Hello Arnold,
Absolutely, I'd be happy to.
The 3B2 emulator is described in more detail here:
- https://loomcom.com/3b2/emulator.html
The DMD 5620 emulator is documented here:
- https://loomcom.com/3b2/dmd5620_emulator.html

I can imagine! The multiplexing code running on the host could get pretty expensive pretty fast, especially with multiple layers per terminal.

*Great* Work, Seth. Congratulations. Hope to see a public release of all
this more than appreciable work (3B2 and DMD emulators) soon.
All the Best for you too.

Neat!
I wrote an emulator for the original 68K jerq/blit two years
ago.
The original Plan 9 version is at
http://code.9front.org/hg/plan9front/file/tip/sys/src/games/blit
A Javascript version is available at
http://blit.aiju.de/
It connects to a public research unix V8 installation. Please play nice :)

Hello Julius,
I am familiar with your work, I was very inspired by it. I'm really glad that the MC68000 Blit is so well emulated! I'd love to see a real Blit or jerq in person some day, but I don't even know where I'd find one (it looks like even the Computer History Museum in Mountain View, CA doesn't have a 68K Blit -- it only has a DMD 5620)
All the best!
