The hardware I'm interested in is:

A) CPU with MMU (FPU is nice but optional)
B) At least 256k ram,
C) Serial port
D) Three hard drives (IDE, SCSI, etc.)
E) Hardware clock
F) Network card (for distcc)

One of the goals of mmy project is to replace cross comiling with native
compiling, and that's the set of hardware I need to get a reasonably
convenient native development environment running under the emulator.
