+ Subject: on PC104 and power
+ Okay.
+ So I'm building an embedded-style system
+ Actually a wearable system - be forewarned.
+
+ I'm looking for info on:
+ how to power this beasty (don't just say "batteries" please :)
+ What other external hardware's needed
+
+ I've found -nada-. Nothing. Zip.
+ MIT's site gives a hint: Batteries.
+
+ Okay. I'm looking at either PC-104 or equiv.
You need a DC-DC module. DC-DC modules take a wide range input (e.g.
9-18VDC) and produce regulated 5V and possibly +/-12V. They come in
different size (power rating), input/output supply ranges, with or
without charger, and even in PC/104 module format.
JDR has some DC-DC modules to experiment with. These are just the building
blocks; you'd have to build a board around it with fuses (input), maybe
some capacitors for filtering and a switch/relay to turn things on/off.
PC104 style DC-DC modules are available from various PC104 module
distributors and have various features/functions. Check the pc104 portal
(www.pc104.com).

+ ...actually I'm also dithering with using a 68K board to build a simple
+ display-toy as well. Anyone know anything 'bout this? There's even less
+ info about this than anything else I've looked for...
You might check out some of the Motorola mc683xx chips. They have high
integration (lot's of IO). Some have LCD support. I think the mc68328
was used in the original PalmPilots and has LCD and/or PCMCIA support.
See ya, -ingo
