I've never lost a line across my screen. And on the 81, I think that the
c9 in it doesn't accelerate it. To my knolwedge, only the 85 has a speed
limiting capacitor. I had a hell of a time removing the capicitor, the
best advice I can give you is get a REALLY sharp soldering iron tip, a
desoldering bulb, tweasers, and be carefull. I use the radio shack butane
cordless iron, and I melted the plastic coating off of the ribon cable in
one place, but it still works. I know a friend that propped his soldering
iron up for a minute while he went to get something. When he came back, it
had fallen off and landed on the U4 ic. It burden a square hole in the PC
board, and needless to say he uses an HP now. You could even try to burn
out the capicitor by over-heating it, and just solder a new 33pf capicitor
to one end of the old one. Be carefull, it takes a lot of heat but it's
pretty easy to burn out a surface mount capacitor. Then you use the
schematic for the switch and the 1pf cap in the accel85.txt file.
