Okay, now is the time for me to ask myself, "What on earth have I gotten in to?" I won a bid on eBay for a $115 CBM 2001 computer for parts. By looking at it the case was in great shape but needed a repaint. When I finally got it I realized that the seller couldn't open it because the back of the lid was tilted in. I used my pliars and pulled it apart to only be disgusted.
I measured 2 millimeters of dust over EVERYTHING and a common house spider as old as the CBM itself. This case hasn't probably been opened since 1978. I plugged it in and lucky as I thought I could be it booted up. I figured the ICs had jolted back into place on the trip so I cleaned the board with achohol and Q-tips, which I still wasn't happy with. There was still a dried on layer of dust. Just to make sure everything still is okay I plug it in and garbage fills the green monochrome monitor. I unplugged it and tapped on the legs of the chips and it turned back on flawlessy. I switched it off and back on and it died again.
At this time I was taking a break because I accidentally stabbed myself when trying to remove the circuitboard so the project was on hold for a few weeks. Yesterday I went to Lowes to get the cosmetics over with. Just a nice hint to any dirty PET users there is a very nice appliance spraypaint called "Biscuit" of all things and it matched flawlessy with my CBM. I also took out all the ICs for a 50/50 achohol-water wash for the board, which made it look right off the assembly line. Now also one pin was broken off one IC and I forgot the orientation and places. Great. I cleaned the pins to find I was suprised it worked at all, so horrendously dirty they were black, but Commodore Computers were quite sturdy in my opinion. I have a fire-survivor Vic-20 and a Commodore 64 that sat on a barn for 15 years. Not really a suprise when my rugged CBM was the most durable with the metal case.
Now I just go to google thinking there will be tons of websites about this just like the PET, but no. I couldn't find anything hardly about it. I know it's a type-2 mainboard but mine is the only model I've seen that has this bluish keyboard. Any help guys? I need to know which ICs go where and the orientation. Plus, to make it better, there is a tiny rip on one of the output on the power supply. Any and all help is appreciated, I'm literally dumbfounded by this.
