 (this is still not documented; I don't know if it is USB, PS/2 or some
 custom thing)

 The keyboard is PS/2 and easy to access.

 From which I/O device?  USB and network require complicated stacks.  SD
 requires a moderately complex driver and, unless you are willing to forego
 the FAT filesystem that is essentially required by the SD memory card
 spec, a FAT filesystem reader.  SD driver + FAT reader could fit in an
 erase block, but we would also need the security infrastructure.
