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.

Sounds like your machine is one of the lucky ones... been through hell, but still works through it all.
