PDP-11 = Pentium Killer?

After your done laughing remember this... At the time the VAX was new in the market the PDP-11 group took most of their standard 11/70 peices and cooked up the 11/74 which was a 4cpu SMP 11/70 and could eat vaxen(11/780) for snacks. That was it's demise... there were only four working 11/74s built before that was crushed. <Hmm, refresh my memory, now what were the PDP-11 instructions to <directly address 4GB of memory? I can't seem to recall any 32 bit <address registers. Look in the VAX archectecture book. <Darn. I've really lost it...how did the virtual memory hardware work in <a PDP-11? Nicely (again the vax is a mostly stretched 11). <Seriously, if you mean the sorta RISC like instruction set in the 11 is RISC?????? PDP-11 is the most CISC machine in the 16bit realm. What other 16bitter is a two address orthoginal machine? <better than the x86 set, then DEC probably would have come up with <something like that. Course, with extra silicon, they could have gone <to 64 bits, and put more cache onboard, then clock it really fast. Then <come up with some catchy marketing name, like Gamma, or Beta, or .... They did called it VAX and when it came time to outvax VAX then comes alpha. Allison
