Other interesting Intel chips (was iAPX 432 (was Re: 88000 machines))

Hi The 432 stuff is really hard to get. I do have another almost as hard to find Intel item. It is a evaluation setup for the i2920, not to be confused with the AMD 2920. It is an early DSP chip. It was Intel's idea of what should be done in DSP. It was not too successful because it was not a general purpose type processor like the TI and Motorola DSP entries. It was designed to do a single program, repetitively. One of the example programs was to make a simple spectrum analyzer. You'd feed analog data in and it would run an oscilloscope as the display. It would just need a anti-aliasing filter for the input and connect to the scope. Some of the other hard to find Intel parts are things like the 8021 and 8022 parts. Although not as rare, the 3000 series bit slice parts are getting harder to find as well but these were used on many of the older Multibus disk controller cards. Dwight
