In my original 1541 manual, it mentions the > U+ and U- commands to change the IEEE speed to match VIC-20 or C-64 speeds. The U+/U- has nothing to do with the actual clock frequency, but with the handling of the bad lines in the C64, that the VIC20 does not have. Any appearance of a bad line during an IEC transfer must be taken care of, and that's why the VC1541 has to be made slower for the C64. Andre -- Email address may be invalid.
