Yes, but so is the ROM in the RCX. The trick was to figure out the upload
sequence (via the serial link) and then Kekoa figured out the format
of the packet.
I'll have to look at the Cybermaster serial code in NQC, but if there
is an ability to place arbitrary bytes in memory, and run code from
an arbitrary address (or fixed somewhere in the limited RAM) then it
is possible to make an umbilical FORTH that does NOT use the standard
opcodes...
I'm not sure about why anyone would do this except to allow operations
that the Cybermaster can't do yet...
