I can tell you I have designed countless instrumentation analog/digital/ controllers around the 6502. it was a terrific lil 8 bit device. I can tell you that the apple 11+ eta-all ran at a tad above 1 mhz. later came a 2 mhz 6502, but it did not by this time find wide spread use. The Sargon programs were written for the apple 11+, 11e with their 6502 cpu chip. Brings back old memories for me Wayne
