as a followup to my NEC uPD7811 series ROM reader i built last year, i decided to try a counterpart for the even older uPD7801
there's no mode pins for disabling/enabling internal memory this time, but i tried to design a simple clock glitching attack to force booting into external ROM, and it works! (albeit somewhat tempermentally)
first random chip from ebay turns out to be from the Casio FP-1000 computer, which was already dumped via other methods, but i have another one to try later

wrote up a bit of info on a less common US revision of Micro Machines for the NES, featuring a pretty nasty bug, discovered just a little too late and then worked around by using a PLD to patch a single *bit*. this is what day one patches looked like in 1991!
