If you use 16 direct page addresses, the question becomes: how many registers are available to the VAX microcode engine? If 6502 is nearly equivalent to what the VAX uses internally, things would be pretty even. I don't have my VAX tech ref with me, so I don't know; if anybody is terribly curious, ask again in about a week, and I'll check it out. >Todd Whitesel -- fadden@cory.berkeley.edu (Andy McFadden) ..!ucbvax!cory!fadden fadden@hermes.berkeley.edu (when cory throws up)
