I had a poster of one on my closet door. It featured the HP-85 in the foreground, superimposed on an outer space background. A comet-tail animation came from the rear of the machine, as if it was coming right at you.
There was also an image of the Capricornus zodiac symbol, for whatever reason.
The poster was given to me by a friend of the family, who happened to be a chemist for the Nabisco company, circa 1981. Even though I owned a C-64 from 1982-1986, my childhood perception was that the HP-85 must have been more of a ''real'' computer.

First computer I ever used. My high school got four of them when HP put a small plant in our town. 20 students, 4 machines, 50 minutes, not a lot of time for debugging our BASIC snowmen and other simple programs since most all of us where hunt-and-peck keyboarders. Good little machines though. Simple, only one cord and no need for printer ink. And as small as it was, that little amber screen wasn''t difficult to read (then again I was using my younger eyes).

When I went to the Byte Shop in Seattle, WA in 1980 to buy a Compucolor 2 they were closing out on (Thank God I bought an Atari 800!). They had some HP-85's. I was really impressed by their capabilities and I drooled over buying one, I couldn't afford them at $5000 (Atari's went for $1200). While I was there a well dressed gentleman came in and inquired about computers for his business. He was shown the HP-85 and said he would take two of them. He pulled out his AE card and the salesman looked very pleased with his sale.

I used the HP-85 back in the early 1980s at the University of Kentucky. The College of Engineering Library had 4-5 of these machines, and I found them fascinating. As a matter of fact, I just found my archive tape of HP-85 code. It''s a pity that I don''t have anything on which to read the tape...*sigh*

If anyone has an HP85 they want to sell, or even just the manuals, I am interested. Heck, even if you could just scan the manuals and send as a PDF.
Maybe someone knows where I can see the manuals online.
Any help would be appreciated.

I can unsecure HP 85 basic programs without password. If someone is interested please let me know.

I saw one at a indoor flea market for $20. Only one I've seen in person wish I had bought it now :(
