| Having fun yet :-) There are a few things you might want to keep in mind when writing ISRs for the RCX... First, avoid calling into the ROM from an interrupt handler. You never know how long they take, and you may in fact be hitting another OCIA (...) (21 years ago, 2-Mar-04, to lugnet.robotics.rcx)
