I probably started it; I just mentioned the PDP-11 one because a lot of
people already have either 11's, or an emulator up and running.

Well, that was an interesting video. How long did it take to get it fully
loaded ?
The "service" Celeron board, is it interfaced internally to the rest, or

Hello Seth,
We were having a 3B2 discussion on the Sun Rescue list, and that got me to

Can you share a status update?
Is there anything us non-developers can do to assist?
