From the project
Homebrew 68040 palmtop computer
This is a work-in-progress palmtop (ish) sized clamshell laptop that we've been working on for a while.
In its current state, it boots up into a BIOS menu capable of doing a few simple things like browsing a FAT formatted SD-card, flashing its bootrom from SD-card and excuting programs from SD-card. One of the included demo programs can play .MOD music files from SD card.
