Does this mean that if we reduce the number of transistors
we can go faster? Let see a PDP 8/Z(1) with current technology
would be? :) I think the problem is computer design rather
than the chip design -- You don't have random access memory
any more & salesmen push clock speed rather than a usefull
measure of computing power.
(1) Zippy - 1000x faster the a PDP 8/E.
Now back to thinking about how to build a homebrew CPU...
Front panel or no Front panel.
