- It sounds like you ran into an HP Integral PC. This was a box based
- around an 8 MHz Motorola 68000 running a version of HP-UX out of rom.
- The box included a 512x255 dot electroluminescent display, 512 kbytes of
- ram, a floppy disc drive, an HP Thinkjet printer, and an HP-IB
- interface. It was available from around 1984 through around 1986 (my
- memory is a bit vague on the exact dates).
-
- The operating system met the AT&T SVR2 specs, ran confortably off of a
- single floppy disc, required no system administration, and - o/s, device
- drivers, window system (HP proprietary), and all - fit into less than
- 512 k-bytes of rom. With an (optional) 2 megabyte plug-in rom card you
- could get all but about 40 of the programs most people think of when
- they think of the Unix* operating system, including a very complete C
- development environment.
-
- My IPC has never needed more than 1.5 megabytes of ram, and could often
- get by with 3/4 megabytes, since the programs reside in rom, and only
- the data has to fit into ram (or on disc).
-
- Sounds like a pretty good system for the time, right? It was, but it
- was in a "luggable" package, and the display was very expensive. It was
- one of the earliest flat panel electro-luminescent displays, and the
- display technology never really came down in price. A fully configured
- IPC (with 2Mbyte rom board, total of 1.5Mbyte ram) would have sold for
- about $8000, which was about $3000 more than a functional equivalent
- desktop system would have sold for. It was just too expensive, unless
- you had a desperate need for a portable box with a unix-type operating
- system. Also, HP-UX included a lot more than just what was in the AT&T
- SVR2 specifications, and the Integral PC never had very many
- applications ported to it, so it was pretty much limited to the
- do-it-yourself software developer market.
-
- I still have an Integral PC at home, and I use it regularly for software
- development, letter writing, and running programs I have written. I have
- also just finished porting Perl 4.035 to it, so it still can be useful.
-
- If it wasn't clear by now, I was involved with the development of the IPC.
- It had its good points and bad points, it was not commercially sucessful,
- and its hardware is now obsolete. On the other hand, if you can find a
- working model, it can still be useful.
