[HECnet] Multics online as node 1.770 (BANAI)

[Jeffrey H. Johnson]

I had a brief conversation with James Wilcoxson (of the PR1ME Series 50 / PRIMOS emulation fame) who mentioned he would be willing to implement X.25 connectivity for PRIMOS ... if he had someone someone else to talk to ... he's using simulation PR1ME Ringnet currently and has his various emulated PR1ME systems networking with that white nicely.

I seem to remember that a major X.25 player used PRIMOS as the backbone of their network.  Which PDN was that?

And, yes, I've used Dynamips X.25 quite extensively over a series of back to back interconnected links, using the Cisco "x25" encapsulation over emulated serial links. I wish there was better documentation as to the lower levels of the encapsulation modes used by IOS.

What is your relationship with Tymnet, Mark?  Are you at all familiar with the operation of TYMCOM/X?

While the ISIS bus of a Tymnet Engine could be fitted with a wide variety of protocol interface cards (X.25 among them), Tymnet's own internal protocol was simply known as "Tymnet protocol", and was entirely its own thing. There were also a number of X.75 gateways accessible on Tymnet, many on satellite links, to allow users to connect to foreign X.25 networks.
