Yes, thanks to one Billy Coore, I have discovered the existence of another Compudyne computer! I'm really excited. (Also, sorry, no Magic Touch Books today...)
Unfortunately, I have found no information on this particular Compudyne, because (as usual) nobody has ever heard of it. The model is PT66HB, and... all I can tell from that is that it had a 66 MHz Intel 486. Yeah, this is only the second Compudyne I've ever seen the model number of, and as such, I don't know how to interpret Compudyne model numbers yet. That, however, is why I want to collect as many Compudynes as possible!
So, I have no idea what the original hard drive size was or how mach RAM it had, but I do know the following. It has the same sound card (Acer Magic S20). Its graphics card is a Cirrus Logic CL-GD5428, whereas mine is a Cirrus Logic 5434. The PT66HB also has a dual-speed CD-ROM drive (unknown manufacturer, but judging from the picture I saw, probably Mitsumi like my dying quad-speed).
Do I want it? Of course! It's another Compudyne! Unfortunately, I have neither the space nor the money, so I will not be purchasing it. Ah well, maybe I'll find another one someday. Here's hoping!
