I have year-old Commodore 1541 disk drive that just went belly-up.
The drive motor never shuts off after the power is turned on and the
C-64 can't access it at all.  I poked around inside with a scope and
all the power supply voltages and clock signals on the 6502 seemed
fine and the address and data lines had activity on them.  Has anybody
had a drive go bad in this way and know what might be wrong?
Alternatively, does anybody know if the schematic and/or ROM contents
for the 1541 is available somewhere?  I hate to spend $100 or so to
fix a drive suffering from a blown $1 chip.  Thanks.
