If memory serves me, I think those old CH PLCs were brand labeled from Sharp (Matsushita) if that helps.

Lol, the demise of the D120 predates the rise of the Internet! They discontinued it in 1984, it's no wonder you can't find anything. Are you sure it's worth repairing? That was not a particularly powerful PLC, even in its day. You could likely replace it with a new micro PLC for less than the cost of repairing those boards.
