Kind of a shot in the dark. But if anyone has or knows of a place that happens to have an old IBM RT (6150 or 6151) I have someone interested in possibly purchasing the system for research purposes.
More specifically, they are looking for a system with the RT version of Pick Open Architecture (OA) already installed and running.
I occasionally try to ask colleagues if they've ever encountered one of these systems, which so far has proved unsuccessful.
Maybe someone on Geekhack has encountered one of these systems before. Send me a PM and I'll get you in contact with him to complete the purchase.
Thanks everyone
