From: Edjik <G.EGK at SU-SCORE.ARPA> RE: PDP-10s and registers Running code in the registers was faster on the PDP-6 and KA. These processors are quite obsolete. On the successors to the KA, namely the KI and KL-10, it is a lot SLOWER to run code in the registers and should be avoided. --Edjik -------
