Dan3, RE:AMD's 29K series "bit slice" processors

You stated that "AMD's 29K series "bit slice" processors were used in early mainframes and supercomputers". This is very misleading and akin to saying that Intel supported the desk-top calculator with a 386 back in 1971 instead of the 4004. The 29K architecture was introduced in the mid-80's and met it's demise in the '90's because AMD could no longer afford the care and feeding of two major 32-bit architectures.

1984-1989 - Weathering Hard Times

AMD celebrated its 15th year with one of the best sales years in company history. In the months following AMD's anniversary, employees received record-setting profit sharing checks and celebrated Christmas with musical group Chicago in San Francisco and Joe King Carrasco and the Crowns in Texas.

By 1986, however, the tides of change had swept the industry. Japanese semiconductor makers came to dominate the memory markets--up until now a mainstay for AMD--and a fierce downturn had taken hold of the computer market, limiting demand for chips in general. AMD, along with the rest of the semiconductor industry, began looking for new ways to compete in an increasingly difficult environment.

By 1989, Jerry Sanders was talking about transformation: changing the entire company to compete in new markets. AMD began building its submicron capability with the Submicron Development Center.

Note: (The AMD 29000 or 29K is another RISC CPU descended from the Berkeley RISC design(and the IBM 801 project), as a modern successor to the earlier 2900 bitslice series (beginning around 1981)).

In the interest of historical accuracy (which I was a part of) ......
