Hello, here's a question for Bil if he still remembers details... How did MOS pick the revision numbers printed on the ICs? The simple ones 'R1', 'R5' and so are not what I'm wondering about, but there were also rather strange numbers that fell out of the standard sequence like the 6567R56A or the 8563R7A and R9B or the 8566R3X. Also, after a while (when the chip was considered stable/bugfree?) MOS dropped the 'Rx' after the part number and only printed the part number on the IC. An indication that this chip was considered 'done'? Examples were the 6526, the 8520 and the 8500 which had R-Numbers at the beginning but then dropped them.
