Opened up my PC20 primarily to check for a battery that might need removing. Turns out they were not fitted.. Decided to press ahead and remove the rust spotted rf shield to cast my eye over the motherboard. Blasted it all out with with air. Check out the HUGE transformer. No fancy switch mode here. Its as heavy as it looks.
Theres spaces for a co processor and extra ram but I dont think ill touch the ram. Computer is too rare to mess with that. I will probably pop in a co pro though as its no stress with since theres a socket waiting for it.
Yes its missing a key but im glad I saved it years ago. Its last working years werent nice I dont think. Some brat had drawn over it with a pen. Pics below which I hope are of some interest. Right now it keeps saying check keyboard so im trying to work that out..
