Yes, Canada had its indigenous computers like the NABU, and they even had at least a few video titlers/character generators. The Scriptovision Super Micro Script comes all the way to you from beautiful Montreal, designed and built in Canada from 1985 to at least 1989. Sold as a prosumer video titler/character generator with a built-in genlock, it turns out to have a 6802 (6800 with internal RAM and oscillator) and 6847 VDG, and with a little work figuring out how the ROMs were scrambled, it is very hackable. I also wrote up a MAME driver in the process so I could understand the hardware. At the end we'll have a new custom ROM, a way to send programs to it over a serial port, and a few sample programs to run.
