Wirelist for HP9000/200 RS232 cable

I am currently fooling about with some HP9000/200 series machines, specifically an HP9816 and an HP9817. The serial ports of these machines are on 50 pin microribbon connectors (like SCSI connectors (!)). They're RS232 levels (1488 anmd 1489 interface chips). I believe the HP98626 RS232 interface card for these machines has the same connector. Needless to say I need to make up adapter cables to DB25 connectors. I assume HP sold said cables at one point, but I can't find the wirelists in any of the obvious manuals on hpmuseum.net (OK, if it's hidden is, say, a printer manual, I'll not have spotted it, but I've read just about every manual for the machines, the interface cards, and the BASIC). I have pinouts for the microribbon connector, so I can work out where most of the wires should go, but there are a few signals that seem to be non-standard (they're driven by I/O port lines inside the machine so what they actually do is software-determined. They're probably not important, but in the interests of compatability I'd like to wire them as HP would have wired them So does anyone have : 1) Wirelists of the original HP cables. I assume there was one going to a DB25-P (male), wires as a DTQ, that would be the most useful to me, but _any_ would be a start 2) The original cables that they can 'buzz out' and produce a wirelist from. 3) A 'spare' cable thet they can sell Thanks in advance for any help -tony
