it’s one of the smallest PCs in the world, with each side measuring around 2 inches square. There’s a surprisingly capable CPU packed away in the tiny chassis with a top clock speed of 300MHz. It’s arrived with us clocked at a slightly more modest 200MHz,but a simple jumper built in to the case enable the processor to be clocked up to either 250MHz or the full 300MHz that it’s capable of.

There’s also 64MB of DDR SDRAM
