Repair & Cleaning a rusty Motherboard of a Commodore CBM 8032
I have received this motherboard of a CBM 8032 to repair from Rossano T.
The motherboard was devastated by rust, many components are short-circuited due to rust that was abundant on the pins side of the chip. Unfortunately the computer was turned on to test it, causing the total breakdown of more components.
I have installed 40 socket because some components are rusty other are dead, however some traces under the chips are eaten by rust and and i had to rebuild.
The repair and cleaning took me a very long time and a lot of patience, it took me about 10+ hours.
Components Replaced:
- 1 x 4650 (6845P) CRT Controller
- 3 x 4116 RAM
- 2 x 2114 Video RAM
- 5 x 74LS244
- 3 x 74LS74
- 1 x 74LS02
- 1 x 1uf 100v Capacitor
Phases of the repair:
ottimo lavoro! ho lo stesso problema sulla MB di un 8096-sk :-( quale prodotto usi per rimuovere la ruggine dal pcb e dalla piazzole?
