(...) This sounds correct. In C, this is how I do it: /* Delete the firmware */ *(char *)0xffcc = 1; (*(void (**)(void))0)(); Indeed, *(void (**)(void))0) is the reset vector, whose value is 0x03ae. 0xffcc is timer 0.

I've used my AC adapter from my 9V trains and I've had no problems. I think you can you any old adapter just make sure that you don't put too much current into the RCX or bye,bye....

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.
