Ethernet cable is paired oddly -- it doesn't have pairs attached to adjacent pins, but the pairs go 1-2, 3-6, 4-5, 7-8. I remember someone trying to do an Ethernet link test with a full 100 meter spool that was wired to adjacent pairs. Lots of bit errors... Anyway, terminal links are slow enough that the pairing isn't critical. We use Cat5 patch cords here at work for everything, including UART connections. It works fine. paul

I had no scanner, and a bit of spare time (OK, too much of it... Plus, I like machine-readable text.) so I typed significant amounts of it in. It is availible here: http://heim.ifi.uio.no/~toresbe/nd/docs There will be more on that site soon. (Al, if you want to, by all means mirror this.) I might easily have made errors in the reading. I hope to make more docs availible as time progresses. There are the beginnings of a Norwegian computer history society, and we may be starting cooperation with some museums with significant collections, but very limited means. They amongst other things have The Collected Documentation of ND (including quite a lot internal stuff) and at least one of each ND machine made. At the founding meeting I'm suggesting we serve the n.c.h.s. website with an ND machine :) I have the files ...somewhere... in PDF and the original SXW documents. The HTML is ever-so-slightly screwed in formatting, especially the bitfield declarations. I have a running ND-120/CX. Like the 100, it's completely compatible with the -10 and the -1. I'm expecting an Ethernet board from an ex-ND friend of mine who still supports them. He's got the board, but most stuff is I'm working on getting the ND-120 online, with telnet logins. SINTRAN is an odd/interesting OS indeed. -toresbe
