After getting the #Commodore#C64 and #C128 running again, the next device to repair is the #C1571.
It had #corrosion and #rust on the main board and the power supply is beyond repairworthiness. I'd replace the latter with a #meanwell RD-35 with 5 and 12 volt output.
One #diode was rusty, a few traces needed #cleaning and five #resistor looked bad. Hope the black hybrid chip is still okay.
Sadly, the lower read head seems to be broken, my work might've been in vain. #floppydrive#retrocomputer
Some more progress on the #Commodore#VC1541 today.
The #alignment from the diagnostics looks okay so far.
But when trying the performance test, it gets stuck at the "formatting" stage. The red LED lights, but the spindle motor doesn't start.
When trying the "fast format", the spindle motor starts, but the red LED doesn't light up.
Both programs, and any other from the diagnostic, seem to freeze until I switch the drive off, resulting in a "device not present" error or similar. #retrocomputing
