I think a totally seperate power bus would be in order. Also I would like to see a big time specification for the connectors, High reliability, gold plated, multiple wiping. 25 pins with interleaved grounds for the data bus, maybe a 10-15 pin seperate power bus. > - Given that Microsoft's NT supports multiprocessors (16 CPUs have > been demonstrated) and Compaq's position as a high-end vendor for > Microsoft-compatible iron, I'm suprised that Compaq is proposing an > I/O architecture that is single-CPU oriented.
