Hi Someone, Ernest, et al.
I did something like this on the Apple ][ , must be 25 years ago now:
http://redskulldc.50megs.com/Flashrom/Flashrom.html
Source code is in the archive if any use to anyone. (6502, but easy to follow)
74LS273 is a good choice for the high address bits, as a RESET can force all outputs to ZERO.
Then you can guarantee a known environment on power up or reset.
Cheers,
Leslie
