AMD 8087 floating-point unit family
AMD published a datasheet for 8087 FPU in 1983 data book "MOS
microprocessors and peripherals". This datasheet mentioned only
5 MHz D8087 coprocessor in ceramic DIP package. It is not clear
if AMD ever manufactured any other speed grades or packages of 8087 FPU.
At this moment (June 1996) there are no known samples of AMD 8087
Information below was provided to us by John Bond:
AMD only made the 8087 for less than 1 year. They started development
after they heard about Cyrix and only made about 20 or 30 lots. The
commercial market for it went down after they jumped in the market and
Intel came out the 80186/80187. I think they sold most of the material
to a company in AZ that tested them to MIL-Specs and re-badged the chips
in their name. Can't remember who that was.
