thinking about a hardware varvara computer. with like homemade chips and stuff
i imagine it'd have an "uxn cpu" that would communicate through busses with the main memory and a "device controller" . the device controller would also be able to interrupt the cpu with a particular address to jump to, except it isn't really an interrupt because in uxn land generally everything runs to completion before doing anything else? i suppose you could try having the cpu save its context (mostly just the stacks) for real interrupts but it might cause problems with any code that modifies itself a lot or expects memory not to change under its feet
