Chris had a fancy wheelchair enhanced with Jon's improvements
took a lot to run those video consoles back then, lots of it was RAM
there was no framebuffer, sprites and backgrounds were rendered real time during CRT gun scans
backgrounds were rendered fro a bunch of tiles to same RAM
of course I 'need' an ESP32 watch :)
it'll be back in Canberra a 3rd time
Jon Oxer won the Rusty Wrench award this year, and it was well deserved
