Home > Projects / Repairs, Today, Various > Restoration and Repair Commodore Floppy Drive VC-1541

I start immediately to say; Floppy Drive, Metal base with the Transformer are ended up in the trash, are unrecoverable (see photo).

What i did is carefully clean the external case of the Floppy Drive which i am quite satisfied of the result.

Then i have started to repair and carefully clean the motherboard of the Floppy Drive (REV 1540050) that had the following problems (see photo):

I had to use the sockets for all the integrated circuits, because the rust had crept under all the integrated circuits, creating many problems.
Remove the voltage regulators and clean the rust that was under the heatsink.
Clean and try all integrated circuits after removing them.
Clean the PCB.
Replaced 2 x 6522 (VIA) that is not working.
Replaced 1 x 6502 (CPU) that is not working.
Replaced 1 x HM6116P (STATIC RAM) that is not working.
Replaced 2 x Resistors of 9.1k 1% interrupted.
Replaced for safety also 1 x Resistor of 91ohm 1%.
Moved the ceramic capacitor (FIX by Commodore) to the solder side, which was fixed above the 74LS86.

What i have used to clean the external Floppy Drive case:

I have used a plenty of running water by rubbing with a brush to remove everything you could do without using specific products.
I have used CIF GEL with bleach that i left to act for 30 minutes.
I have rinse thoroughly with water, always rubbing with the brush and with a stanley plastic spatulas
I repeated these last two phase for least 3 times.

I have used CIF Degreaser with Bicarbonate that i left to act for 10 minutes.
With a Brush / Toothbrush / Toothpicks / Cotton Fioc / Stanley plastic spatulas o have rubbed and cleaned the most dirty and hidden parts.
I have rinse thoroughly with water, always rubbing with a brush.
