Anyone ever heard of a Canon BX-1?

I have recently acquired a Canon BX-1 Desktop Computer. It's a self-contained unit incorporating an alpha keyboard, a single-line alpha display, thermal printer and 5.25" disk drive. From the markings on the keyboard it seems to be programmed in some dialect of Basic. Does anyone know where I can find any information about this machine? A web search turned up exactly one page mentioning it, which didn't tell me much. It didn't work at all when I first switched it on. I found and repaired a fault in the power supply, but that doesn't seem to be the end of its problems. At switch-on, it beeps, and then starts flashing a row of up-arrows in the display. There is *almost* no response from the keyboard, except that after about 20 or so keystrokes it flashes something like KEYBOARD OV'FLO very briefly and then goes back to the up-arrows. Is there anyone out there with any experience with one of these things who can tell me whether it's trying to signal some sort of error condition with the up- arrows, or is it just totally insane?
