I dunno, I haven't seen one. The 1Mbyte limit was reported elsewhere

It net-boots Ultrix but not NetBSD? That's _very_ weird... What's the
start address of the Ultrix kernel? 0x80030000?
Or is the Ultrix kernel on disk?

I'd try removing the lead from the Ni-Cad battery pack for about 5
minutes. The 5000-series machines have integral power on the clock
chip, AFAIK, and do you have to jumper the NVRAM off (or short it.)
I don't get what you say about the graphics, either. AFAIK, 3100s and
2100s have the same VRAM socket with either mono, colour, or nothing at all.
