I was digging through an old parts drawer and found an old complete HP360LX palmtop computer I remember buying it from Tiger for cheap. It has a CF and PCMCIA slot, should support some network cards and it has a serial port on the docking bay.
As these units are somewhat cheap if you can find them, they might be handy for a robot or automation controller (WiFi, RS232)
I've found very little info on these old beasts via Google, but something old is new again **broken link removed** 360LX runs with 2x AA (and can charge NiMH/NiCD)
Squeek, that's about it. It's only a 60MHz CPU. But they make color versions and the very old DOS version 200LX http://www.rundel.net/palmtop/datasheets/hp_360lx.htm **broken link removed**
The 7.91MHz 80186 based 200LX with MSDOS **broken link removed**
Marks256 you like old silicon so I'm sure you'd like one of these. The Atari Portfolio **broken link removed** John Conner used one to hack an ATM in Terminator 2
I like DOS. It is the one thing M$ did right. Then again, that is all i had when i first started with computers... If i remember correctly, my only OS i had was the windows 98 boot floppy!
