Picked up a pristine 386SX-16 system, but it doesn't look like the MHZ display was ever set up correctly. As I found it, the pins moving left-to-right on CN1 were connected +5V, GND, and then a yellow wire that was left hanging in the case. I've tried connecting this to the Turbo LED header and manually pulling to GND or +5V, but the display never changes. It just stays at 16. I've tried searching online, but there's no identifying information on the board and I haven't found anything that looks similar. Anyone have a pinout or is it just something I'm going to have to guess-and-check? Thanks.
