I'd been scribbling schematics for a Z80-based wearable for a while at the nearby diner, but trashed the idea because I didn't want to write the software... Basically, it was a Z80 cpu, a couple of PIOs, an 8250, and a sortof-MMU (address decoder hooked to latches and another address decoder), 1Mb RAM (32K ROM, 16K non-paged, 16K paged). My reasoning was that a Z80 could run for ever on very little battery power, and would be more than enough for checking email (via amateur packet) and text editing. With a couple of nicad AAs backing up the ram. But a very kind fellow gave me a 486 laptop, which is now my base. IMHO, the gameboy would be hard to hack, due to lack of hardware docs, multilayer board, and SMDs. But if you want my schematics, I shall try to find a scanner... OT of Z80: I'm looking into getting 68K Linux running on an old Amiga 600 with an 030 accellerator+FPU(sp?). It seems (to me) that this would be a really nice wearable machine (though I could be a wierdo), as it has NTSC output, internal 2.5" IDE, and a VERY small size (think the QWERTY part of your keyboard). The CPU+030 costs around $400-500US. Plus a PCMCIA socket, yes, though I think it's type 1. I'd probably rip out the floppy drive and replace it w/ batteries+regulator. Moan. Then there's always my old Mac LC2, but the video for it would be a big pain. Kent Lofley wrote: > Has anyone thought about using a gameboy as the base for a wearable.
