Here is a Kohjinsha SA1FO from 2007 (looks much older).
Here are the specs:
Single-Core AMD Geode running at 512MHZ or so with integrated graphics
512MB DDR1 ram (I'm fairly sure it's not DDR2)
60GB Hard drive (I dunno the RPM)
1x USB 1.0 type A port, 1x USB 2.0 type A port, 1x VGA port & 1x Ethernet port.
The keyboard fell out, and I lost it. It didn't work before it fell out anyways.
Running Windows XP.
