In other words, could we get an 8500 (say), plug our > unibuses and massbuses in, and then boot 4.3? Or is that impossible. Unfortunately, the VAXBI to UNIBUS adapter is not transparent, there is a fair amount of configuration involved. Also, there are certainly other machine type dependencies in running UNIX on the new VAXBI CPUs. DEC has ULTRIX V1.2 running on the 8200 and I suspect that the 8500 and 8800 are close behind. ------
