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. :-(

	Thanks, Ken
