For those of us stuck with a SpeedStar 24 bought before it became
apparent that Diamond was determined to be a corporat a**hole, does
anyone intend on obtaining the non-discloseable dot-clock setting
code, creating a clock-frequency program and distributing it in binary
form (not violating the non-disclosure)?
If so, I'd be very interested in hearing about it/from you.
