(Here liney liney liney... Where is that line eater?!)
I have need of a 1541 service-manual with schematic and test
procedures. My problem is this: after the disk is on for a short
while (~15 minutes) it locks up while loading a program. After the
LOAD-command the system responds with its "Searching for" messages and
then just sits there, with the drive still spinning. I've replaced
the 12-volt regulator and the 74LS14 (hex-inverter) chip, with no luck.
Any ideas or suggestions would be appreciated.
Thanks in advance,

I happen to have a repair manual sitting right in front of me. It was just returned by a friend. It is called "Commodore 1541 Troubleshooting & Repair Guide". It is written by Michael G. Peltier, and is published by SAMS. The book has schematics, flow charts, and lots of diagrams. It also has allignment procedures (with & without an o'scope). It also covers the old 1540 drives, as well as the 1542 drive (the 1541 with the "lever" door). Cost is $20.00 and can be found at B. Daltons. Good luck with getting it fixed!!!!! -- ------------------------------------------------------------------- Dave Lowrey "So it goes, so it goes, so it goes, so it goes.
