When I put the 1.44 mod into my STacy, it wouldn't work with the WD1772 that was on board at the time. It was
an 02-02 chip, of which 95% of them work correctly. I had the 5% version.

Actually, they are still available. Best Electronics has them - I bought one for my STacy - it was on sale at $29.95 US.

What pin does it go to? With Sean's mod, pin1 of the YM2149 chip can be used as a ground, and pin19
is for the DS1 line, also you can get 5v from pin40.
