tim shoppa: :But you can't just run an Apple I emulator on the Apple II. The :memory maps are completely different and the video chain of the :Apple I is radically different than any home micro designed since :the late 70's (i.e. it is *not* a memory-mapped video system; it's :closer to a dumb terminal bolted onto a 6502. Well, a really dumb :dumb terminal :-) ) hell, you can emulate anything on anything. it'd just mean you had to emulate a 6502 on a 6502 and trap the pesky screen-write instructions. then again, some things are better left undone... ;> for the benefit of the unenlightened (ie. communa), could you please decsribe the principles of the apple i's video system? thanks. (or point us in the direction of such a description.) -- Communa (together) we remember... we'll see you falling you know soft spoken changes nothing to sing within her...
