It would be handy if there was a word that
deleted firmware. It is often inconvenient
to get at the batteries. At Kekoa I see the
opcode but no rom entry point. Trashing
the header in memory and jumping to the reset
vector might do it. I wonder if anyone has
figured this one out. Seems likely. Where do
you ask questions like this? robotics.rcx
maybe?

I guess I should really upload the rom image
and disassemble it to see how the opcode does
it.

Kekoa, feel free to jump in here...

Personally, I think just jumping to the reset vector 0x0000
should do a total cold start, right?

Cheers,

(...) As a guess the following string tells the ROM that there is valid firmware. This might need to be stepped on before jumping to the reset vector. .string "Do you byte, when I knock?" (25 years ago, 16-May-00, to lugnet.robotics.rcx.pbforth, lugnet.robotics.rcx)
