- I've got a nondescript XT multi-I/O card (1P, 2S, FD, clock) with only
- the name KM-516 on it. There's a MM58167 clock chip and battery on the
- card. However I don't know the I/O address of the clock. By looking at
- all I/O ports with IOVIEW I found the top nybble of port 277 was
- changing rapidly. My guess is that this is the 1/1000 second register.
- I also guess that I have to write to another port to select the clock
- register to read. Where would that be? Does anyone know for sure?
-
- If you have a full set of jumper setting for this card, that would be
- even better. I had to figure out the serial port jumpers by following
- traces. :-(
