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, Mike
