Well, at work actually - found a few years ago when Estates wanted to turn off the power to a little-used plant room, and called me up to say "is it OK to turn off this network thingy?" I couldn't believe it when they described it ("lots of plugs and sockets, some lights"); it was still running! Of course it hadn't spoken to anyone or anything in over a decade so I just did my bit for carbon reduction by repositioning the mains lead... I don't remember much about them either, so I'll ask a couple of guys who might remember more. Try 300 baud on port 0 for starters. -- Pete Peter Turnbull Network Manager University of York

So these were call "Triple X standards". It was Janet so they just had to be different. The PAD had extensions to X28 and they had their own extra "Standard", TS29, which was X.29 over Yellow Book Transport(YBTS). From what I recall YBTS does not map well to an OSI transport service but it did allow traffic to be routed across multiple disperate X.25 networks. So in the UK the Post Office (later BT) X.25 Packet PSS network had addresses starting "2342". As you couldn't get an official allocation for a private X.25 network Janet used the range starting "0000". If you wanted to route a connection from a PSS link to a Janet site with no PSS addresses you had to use a relay of some kind. YBTS added an extra layer and allowed through routing. I think I still have the BT manual which lists the numbers and addresses of its dial-up notes.... Dave G4UGM Practical X-25 networking Alan Buttle (and others) ISBN 0-9508677-0-5 may be informative on X.25.... ... and a search on Wikipedia reveals some of the standards are now freely available from the ITU... http://en.wikipedia.org/wiki/X.25 and links at the bottom

Tony Thats great. Think i just need the 'how to' for getting console access. I can prob figure out the rest. Its also not clear if the main code is booted from the network (implied in one google search i found) having said that there are a lot of eproms on the memory card so hopefully all the operating code is in the box.

The problem is that on top of that is a pile of HP41 docuemtaion, a couple oh HP82161 tape drives, 6 HP41 calcualtors, etc.... I do want to extract it carefully. As ever, I don't have a scanner, but I can probably make a copy of the manual and post it.
