About a year and a half ago I wrote an overview paper on RISC architecture for a class that I was taking in Computer Management. I asked Herbie Chong, from the Watson Research Center in Yorktown Heights, what had become of the 801. I paraphrased his e-mail responce as follows: "Finally, the 801 is used as the processor controller in the IBM 3090 mainframe. A processor controller monitors all memory, device controllers, I/O channels, and handles console interaction when the 3090 itself is unable to do so." I beleive since that time the UUCP machine at Yorktown Height, polaris, is no more. So I don't even know if anyone there is on the net and can offer their insights. George W.
