We've been talking about how to put our Alto(s) on the net, with IFS running
on TOPS-20. We'd be very interested.

Wow. I'm totally stunned! Do you have any 3-Mbit transceivers to go with them?
If you (or anyone) need, I can provide old code for an IP/PUP router to
connect a 3-Mbit Ethernet to a 10-Mbit (if you want to put, say, an Alto on
the Internet - not sure if they ever did a 10-Mbit card for the Altos). It
would need either a UNIBUS 11, or a QBUS 11 and a QBUS->UNIBUS converter. (The
DEC one is UNIBUS->QBUS, so would not help us.)

Another rara avis! (I don't remember if they ever made any QBUS ones.)
