It's for sale in Canada, for about 6 months I think. Don't think they sold many tho'.
The court ordered sharing of the IBM Principles Of Operation (POO) deal ran out in the early 00's. At this point HDS (who was phasing out the mainframe) and largely Amdahl could not afford to pay the price that IBM demanded for access to the POO. Amdahl had a 64 bit CPU up and running in development, and was getting ready to announce when this happened. That was it, Amdahl kept selling the 31 bit CPU for a few years, but it was over at that point.
