Original Documentation: ==================== Getting to Know Your PS/1 Computer Drive and Adapter Card Installation Reference System Board Reference Keyboard Notes: ============== The M2 keyboard is the keyboard that came with this system and has a known and documented issue with the 2 capacitors on the enclosed circuit board. The keyboard eventually stopped working. I disassembled/reassembled the keyboard and had the capacitors replaced at an electronics repair shop in town. Unfortunately this shop did not do a "great" job. The keyboard works but generates a BIOS "keyboard error" on boot up. Tapping the [ Esc ] key clears the error and continues to load the Operating System. The keyboard and lights then work as they should.
