If I'm on the right track, then I do need doco for the HPC1.5 chip. The docs for HPC3 are on oss.sgi.com, and at the
moment I'm trying to get the doco for HPC1.5 off them.
The SCSI, Ethernet and serial I/O etc chips all hang off the HPC chip (according to the circuit diagram in the MC
document), so my assumption is that I need to figure that out, whatever happens.
Am I right there, or am I making things too complicated again?
