Does 2.9 BSD with TCP/IP (assuming such a thing exists) fit on those machines? (I know 2.9 does run on them, but I don't know about the TCP/IP part.) The reason I ask is that MIT did a TCP/IP for V6 which would run on them (only incoming packet de-mux is in the kernel - the TCP is in with the application, in the user process), which has recently been recovered from a backup tape. I'm trying to figure out if there is any use for it, as it would take some work to make it usable (I'd have to write device drivers for available Ethernet cards, and adapt an ARP implementation for it).
