Canadians, rejoice! Not only do you have curling, the Big Turk and Tim Hortons (and, when I was in BC last, Dr Pepper made with real cane sugar), you also have a number of interesting indigenous computers like the underappreciated Micro Computer Machines MCM/70 portable, the Tarot Electronics MIMIC (not to be confused with the more notorious Spartan Mimic), the Dynalogic Hyperion and of course the NABU Personal Computer. And, like your neighbours to the south, you have terminals too, most notably the Telidon and Alextel.
Terminals, however, are in many cases based on general purpose architectures, just lashed to restrictive firmware — a good example would be the DEC VT220 which is controlled by our old friend the Intel 8051 — and game consoles likewise fall naturally in this category. Plus, there's a third group of computer-adjacent devices that qualify as well: the video titlers.
Video titlers (also known as character generators) are exactly what they sound like: devices that stamp bitmap data, usually text, on top of a video signal, like this typical example from a 1992 demo video for the consumer-oriented Videonics Video Titler. Distinct from what you might do as part of an editing system, many of these machines operate in real-time and over live video input such as the classic Chyron systems. Today's titlers are usually add-on boards controlled by a standard desktop computer, but for much of their existence they came as standalone devices with their own CPUs and video hardware, and that means they can be potentially hardware-hacked like anything else.
Well, Canada, you have your own indigenous video titlers as well, and here's one designed and manufactured in beautiful Montréal: the Scriptovision Super Micro Script, circa 1985.
The Super Micro Script was one of several such machines this company made over its lifetime, a stylish self-contained box capable of emitting a 32x16 small or 10x4 large character layer with 64x32 block graphics in eight colours. It could even directly overlay its output over a composite video signal using a built-in genlock, one of the earliest such consumer units to do so. Crack this unit open, however, and you'll find the show controlled by an off-the-shelf Motorola 6800-family microcontroller and a Motorola 6847 VDG video chip, making it a relative of contemporary 1980s home computers that sometimes used nearly exactly the same architecture.
More important than that, though, it has socketed EPROMs we can theoretically pull and substitute with our own — though we'll have to figure out why the ROMs look like nonsense, and there's also the small matter of this unit failing to generate a picture. Nevertheless, when we're done, another homegrown Canadian computer will rise and shine. We'll even add a bitbanged serial port and write a MAME emulation driver for it so we can develop software quickly ... after we fix it first.
