However, few if any were sold, and it disappeared without a trace, leading to BiiN being retronym'd "Billions invested in Nothing". The i960 was how Intel repositioned it to try to salvage as much as possible. Most i960 variants either don't have the tag bit hardware and object-oriented "microcode" that was used for BiiN; it is only officially present in the i960MX, but might also be in the i960MC. I think only the MX and MC have an MMU. It should be possible to port {Unix,xBSD,Linux} to the i960MC, but I don't think anyone has.
