I found an HP150 (model 45851A?)--how do I make it work?

Hi Frank, The terminals I'm thinking of would be reasonably old. For the life of me I can't recall HP's designation for them, other than it probably began with a "9" and had a suffix of "A". They had rounded edges, and like the HP-150 II allowed the tilt of the screen to be altered. You couldn't really stack anything on top of them since the top wasn't entirely flat - the frontmost couple of inches was angled up slightly. Maybe I'm thinking of the HP-120/5 then? I'm sure I've seen a photograph of an HP micro which looks almost identical to one of these terminals. TTFN - Pete. -- Hardware & Software Engineer. Sound Engineer.
