Re: 486 PC. Keyboard problem.
Just for reference, I couldn't identify the PC or motherboard manufacturer. It uses a double sided riser board fitted with a VGA card, an FDC card and several com port cards.
Three com ports are used. One for an external serial printer, one for the machine's internal keypad and one to control the machine.
