I picked up a 3B2 400 and an AT&T 5620 "BLIT" recently and am always looking
for software, folklore, discussion to supplement their restoration.
I just don't know if a listserv is the right venue to collaborate on. But I
don't have any better ideas.
Any content and software people have collected, I would be happy to host on
one of my Azure machines for distribution.

Internet for many years, as it appears/disappears, and I have pretty much
zilch for internal HW documentation. I'm sure you are aware that this same
discussion is taking place over on the Classiccmp mailing list.
