Re: What the hell is C++, Java, C# and the other drivel?
PDP-8s required it because standard practice was to store subroutine return address in the location immediately before the subroutine. Also, the PDP-8 had instructions that saved time by leaving the memory location cleared, so it was not necessary to rewrite the read value back into core.
I actually liked the PDP-8, it made you feel that you actually understood what was going on right down to the gate level.
