[sdiy] MiniWave EPROMS

[Happy Harry]

Yeah yeah....

Even 16 is unmanageable when its your wife turning the dial
and the led indicators read in straight binary. I'm going to make
a numeric display to retrofit, probably a 2 digit 00-08 10-18 sort of
like an old Korg. This should help out a lot.

I'm just quantizing with it, so the ROM is WAY too big for me now...
