HP Integral PC

The Integral PC (model 9807A) was a portable Unix workstation released by Hewlett-Packard in 1985. Operating system ran from ROM; software would be run from built-in 3.5" floppy drive, or from an external hard disk attached to HP-IB bus.

The OS is HP-UX, originally version 1.0 based on AT&T System III, later upgraded to 5.0 based on System V. Neither had TCP/IP networking support, but serial interfaces were available (supported by Kermit and UUCP software).

MAME emulates essential parts of the IPC:

  • keyboard and mouse
  • graphics processor and monochrome display (512x255 in the standard model, 640x400 in unreleased prototype)
  • internal floppy drive
  • memory expansion (up to 7 MB)
  • HP-IB (IEEE488) controller

Not emulated: built-in printer, sound generator, any of the expansion cards.

Software is available from HP Museum and other sites, and is documented in MAME softlist.
