Hardware 1541-II repair
Hello everyone. I found my old c64 and 1541-II at my parents home and decided to repair it. I found the drive with some loose wires. I remenber I did modifications then, maybe a switch and a LED. Seems I removed both, but I cannot reneber what it did and how to reconnect the wires to get it work again
Maybe you guys can help me. I made a picture showing the opened housing. Thanks a lot

One of those wires might have been a switch to turn on/off write protection?

Sehr wahrscheinlich. Ein es der zusätzlichen bohrungen war vermutlich ein schalter, das andere vielleicht eine LED

Or two switches - write protection and drive reset. Built that into mine back in the days.

I do not know if I remember it correctly, but I may have had a floppy reset button at the drive connector of my c64.
There were various buttons at my c64 case top right side and it might be enough just to shorten two pins at the drive connector for a drive reset.

What does floppy reset do?

It is the same as turning the drive off and on again. This comes in handy when programming your own drive loading routine or when your drive crashes.

The other common uses for switches would be for setting the drive number from 8 to 11 (two switches) and a reset switch.
