PDOS-generic (and PDPCLIB) now have a 64-bit (x64)
EFI target.
I tested on modern hardware (that was unable to
run PDOS/386).
It's still proof of concept.
It's also an interesting concept - if you just have PDOS-generic
as-is, can you reconstruct the world?
I provided fill and zap, but not hexdump.
You can't launch new programs yet, but the bios will
enable you to change what is launched (or launch
a new thing after pcomm exits).
