For those who might have a project for which a Palm might be a bit much, the
October 2000 issue of Elektor magazine has a project using a Gameboy as a 2
channel oscilloscope. A card with EPROM, Maxim A/D converter and Dallas digital
pot chip plugs into the ROM port of the gameboy, and if the pictures of the
screen are to be believed, makes a very presentable scope.

Apparently the gameboy uses a Z80 derivative, so it should not be too hard to
hijack this concept for a PIC->Palm communicator type of deal, using a gameboy
instead of a palm.

For those who do not know Elektor magazine, it is of European origin, translated
into several languages including English. Website at
