Wang produced a number of computers with the 2200 name over the course of twenty years or so. What was it that these machines had in common that they formed a family? The answer is almost 100% upward software compatibility and to a lesser degree, I/O peripheral compatibility.
The subsection links are arranged to describe a few facets of the 2200 family.
2200 CPUs Wang produced three generations of CPUs; that is, the CPUs were not compatible at the microcode level, requiring Wang to implement the Wang BASIC interpreter from scratch for each. There were comparatively minor changes within each generation, such as improved packaging density or increased microcode storage.
2200 Systems Wang would bundle and package different CPUs, peripherals, and storage systems and sell complete systems. This section attempt to present a rough outline of that history, although things were too fluid to actually describe every combination of systems Wang ever sold together.
Peripherals This is just a quick section enumerating all of the many peripherals offered over the years. Some peripherals were OEM'd by Wang, but most were home-grown designs. The I/O system of the 2200 family was unchanged from the first product to the last, so often users could upgrade to a higher end system without having to buy all new peripherals as well.
Iskra-226 While Wang was still producing the 2200 family, the Iskra-226 was developed in the Soviet Union. I have little information about it, but it was a clone of sorts of the 2200.
Fasstcom Computers After Wang ended the 2200 family, a former Wang engineer obtained the rights to use some of the technology, and founded Fasstcom Computers.
If you have any information on the Wang 2200 family (manuals, schematics, sales literature, etc.), or you worked at Wang at the time, or you have any revisions to my reconstructed 2200 family tree, please contact me.
I'm also interested to learn more about Fasstcom, the Iskra-226, or any other Wang-2200 related systems.
