Re: R40

The roms are interleaved, for example:
offset $34D0 in 2.20 roms:
LO ROM: TA R STEINRMIO
HI ROM: CS03SY MOFTA N

actual string here: "TASC R30 SYSTEM INFORMATION"

"R30" is in more than 1 place.
Is your plan to change all of them to "R40" and put new EPROMS in your chesscomputer? Then unfortunately it won't work. You'd have to recalculate the ROM checksum too. The system does a self-test and will lock up if it fails.

Even if you manage to do that, it's still not a "real" R40. It's just play pretend, right? :P
It's also possible that Tasc did a few more changes. For example a longer delay for the beeper so it doesn't have a higher pitch at the 40MHz clockrate.
