There should be an "International RAMless Programming Contest", the competitors are required to write the most innovative and/or useful program by doing computation in-place, in the CPU registers, without using RAM.

Teams are divided according to different CPU architecture (RISC CPUs obviously have an inherent advantage). A adequately sized ROM is provided, preferably not too big (to stop people from putting a huge lookup table in ROM), and a standard output port is specified.

@niconiconi what about caches? Modern CPUs have more L1 cache than my first computer had RAM and disk storage combined...
