?? about at29c256, replacement chips
usaully a faster chip can process data the quicker. the replacement chip: at29c256 operates at 90ns ..would a faster 120ns chip perform alogithum functions quicker? does this apply to the 29sf512 as well?
seem like the burn1 unit will program the 90ns, but will it do the faster 120ns?

Actually the 90nS chip is faster. But either chip will work fine. Because the ECM is slower than either chip
Also your burner should support either chip as long as it can burn the type number. It don't care about access time.
