Wanted: some HP 9000/3xx bits

The rest of the slots use two DIN connectors, a la VME and other busses. One looks like a standard VME connector, the other is reverse gender IIRC and about a third the pincount. I'm wondering if these slots are the DIO-II that I've seen mentioned, or some other designation. At the moment I don't need to fuss with it, as there's a 16550 on the system board with what looks like a standard "DB9" connector. But thanks for the info, it may come in handy later. Hopefully it will turn out to be a working example, and I won't need to open it up! I remembered quite liking the keyboard from an HP 700/22 terminal many years ago, but don't especially care for this one. The keys are very loose and wiggle around / rotate on the mechanism, and the pitch/width of the keycaps seems to be enough smaller than my Thinkpad keyboards that I'll be fumbling a lot. I know there are converters to allow the use of standard keyboards and mice, but at the moment I'm thinking of sticking with more-or-less stock parts. Just wondering if there are other HIL keyboard options. Thanks for the info! --Steve.
