Out of the annuls of history comes this interesting computer on eBay. PIXAR made around 300 of their Image computers during the late 1980s, hoping they would be a commercial success, as well as useful for their own render work. While they proved to be very good at what they did, they were a bit ahead of their time, and certainly out of the price range of most institutions. The first models started at $130,000 and the PII, as seen on eBay, was sold for $30,000. PIXAR began trying to sell their computers two months after Steve Jobs bought the company (formerly LucasFilm graphics division).
Each system ran 1, 2, or 4 CHAPs (CHAnnel Proceesors, RGBA). Each CHAP consisted of a board with 4 AMD 29116 16-bit bipolar bit slice microprocessors, running at 10MHz supported by 4 Logic Devices LMU17 16 x16 parallel multipliers.
Essentially the PIXAR Image Computer was a 1980s GPU, it required a separate SGI or Sun workstation to run.
