This one is overclocked 33mhz, that explains the cooler on the cpu, however my IR thermometer told me the VLSI chip was also getting
very warm under full load as well, in-fact more hot then the cpu.
I have a tray of 3.6v lithium batteries that are like new, so i am recycling them, the wires are soldered on, it is 100% non destructive add, solder can be removed with wick.
Thanks for posting that link to the pram batteries, 2 bucks free shipping is a deal.
