Hi Mark, At first we just used PSI that talked to a DUP-11 in a VAX-11/780 and later a 750. The DUP-11 then talked to a modem, and thence to the JANET academic network in the UK.
Later we used PSI-Access which talks directly to Ethernet. At least that is how it appeared to me. Your point about being able to build a cluster and communicating to the outside world using UCX or Multinet is perfectly correct. I have done it. HOWEVER, that does not let me use the (admittedly ancient) network software that sat on top of PSI/PSI-Access, and that is what I am hoping to achieve. My reason for wanting to do this is simply to recreate past glories. I admit it is not that useful, but this is a hobby, right?
