Some guidelines: - make source photo perfectly perpendicular before you start tracing - no fancy stuff like glow effects or beehive pattern (see other SVGs) - keep colors consistent for all vfds - put segment ID in title tag as y.x where y=grid, x=plate (the ones by Kevtris need to be descrambled to match actual MCU write values but that can be done easily afterwards)
I don't remember if Coleco Zaxxon's MCU was identified.
