Retrocomputing

I'm interested in old computing devices. Mostly machines made before 1982, but with a few exceptions. Some of these machines are well known and were very commercially successful. Others have faded into obscurity, despite having advanced the state of the art.

I've tried to provide some technical information of a few of the interesting machines. Unfortunately I don't have very much time to spend on this endeavor.

Generally speaking, nothing listed on this page is being offered for sale, except perhaps the items in the trade section.

The Central Research Institute for Physics (KFKI) in Hungary made a series of computers called Stored-Program Analyzer (TPA). Many (but not all) of these machines were clones of DEC machines.

Western Digital

Western Digital is now best known as a disk drive manufacturer, but their origins are as a semiconductor company. At one time Western Digital was the leading manufacturer of calculator chips. Some of their more popular computer-related products included UART chips and the 1771 and 179x floppy disk controllers.

In the mid-1970s, Western Digital designed an NMOS microcoded 16-bit processor chipset for the DEC LSI-11. With different microcode, it was offered as the WD16 (used by Alpha Micro). When UCSD Pascal started becoming popular, microcode to directly interpret p-code was made available in the form of the WD/9000 Pascal Microengine chipset, the WD/900 board, and the WD/900 box.
