I had kept some Sun2 bits around to build a 3 to 10 bridge with a Sun 3mb card. I would be interested in the code for an 11. Somewhere, I might have enough of the Stanford code around to do it with a SUN CPU card. Of course, now you could do it all with an FPGA and embedded ethernet microcontroller. If we were to get an Alto running again at CHM, I'd like to get a simulated IFS going to Etherboot against.

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.

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.) Noel
