Tell me why did you use the RAM I/O chip, instead of a UART or something similar, when the machine had separate RAM?
Answer:
Science of Cambridge used 8154s on its MK14 kit (National SC/MP based) and so they were available when we needed something for the 6502. They were fairly cheap and the extra RAM was a bonus, even though it meant converting from 6502 clock/write to the read strobe/write strobe that they used.
