Re: Author comment -- could you lot miss the point any more widely?
The VGA, PS/2 keyboard bit sort of plays up the historical and wearing-the-sweater-to-the-last-pill (missed the easy germanic word, sorry) sensibilities and gilds the age of the pre-U1...U3 microSDHC. Just the sort of thing for playing Assassination Classroom in public; can Team Bluebottle find vulns in Team Oberon? Only perhaps this sticks one with exposing a pad with the JTAG pin or feeding it an ASK antenna.
Playing on Hardcore you'd have to bring tree frog/caterpillar blood antifreeze or some other rite of spring (...for 10y.o. if I'm reading this right, so caching freshwater might be in there...) into the competition.
The FPGA is a perfectly sensible inclusion; no need for 10k seat licenses on there until you lock in Knight's Bridge wordlengths (500-bit?) at scale. It would make it uncomfortable for the wearer to have to dissipate top-line SHARC or FPGA...you'd know your sweater shorted it or you'd been found vulnerable.
I am looking forward to the next XMOS thing.
