PC532
The PC532 was a "home-brew" microcomputer design created by George Scolaro and Dave Rand in 1989-1990, based on the National Semiconductor NS32532 microprocessor (a member of the NS320xx series). Full hardware documentation for the design, including schematics and PAL programming data, was made freely available, and a short run (around 200) of motherboard PCBs were produced for hobbyists to populate and assemble into fully functional systems.
Hardware specifications
Operating systems
The following operating systems were ported to the PC532:
- MINIX
- A port of MINIX 1.3 to the PC532 (sometimes referred to as MINIX-532) was released by Bruce Culbertson in 1990.
- Mach
- Mach 3.0 was ported to the PC532 in 1992 by Johannes Helander, Tero Kivinen, and Tatu Ylönen; some work was also done by them on porting a Net/2 BSD-based Mach server (bnr2ss) to provide BSD UNIX emulation.
- NetBSD/pc532
- A project to port 386BSD 0.1 to the PC532, initially called 532BSD, was started by Phil Nelson. This was integrated into the NetBSD project in 1993 and became NetBSD/pc532, with Nelson as the port maintainer. On January 9, 2008, NetBSD/pc532 was dropped from the NetBSD source tree, as GCC support for the NS32532 microprocessor had been dropped.[1]
