Types of S100 Bus Users

These are people that just want to have a nice computer museum of their own to feel proud that they grew up with the technology and have both the space and money to show it off to their friends and family.  They frequent places like eBay to obtain S100 boards.  Unfortunately because of our age S100 boards are now becoming fairly common.  Nevertheless a complete working Altair, IMSAI, Compupro or Cromemco S100 bus system can reach several thousands dollars.

The Hardware People
These are people that just like fixing up old stuff ... the nostalgia of the days when radios, stereos, TVs and computers were repaired in a little neighborhood fix-it shop, and they enjoy making the old hardware work again while also  building new boards for the fun of board assembly etc. This is the main focus of this site.  We utilize the IEEE-696 S100 bus to design and use new board hardware.  We have so far,  (just for CPU boards alone), new boards for the Z80, 8080, 6502, 8088, 8086, 80286, 80386, 80486, 68000, 68030 and PDP11, Edison,  Raspberry Pi and Arduino/Atmega CPUs.

The Software People
These are people that have been creating the SIMs and emulators that run on PC's etc. but emulate S100 bus hardware.  They are also endless descriptions of CPM BIOS'es with software available today for almost every S100 bus soft or hard disk controller.  Many also take pride in booting up CPM and displaying a directory etc.  However few today ever use these systems to write new software. If done at all it is done on a PC emulator.
