The Amstrad PenPad 600, one of the first PDAs ever (released back in 1993), sporting a 14.83 MHz processor, 193 Kb of memory and the obligatory monochrome touch screen, can be yours for only a few euros. Interested? Good, check this German e-bay.de auction then. It's all about a fully working, boxed PenPad with a German manual. Seller ships only to Europe.
