Just checked the manual for my 164sx, and yes, it does need the fan tach.
I'll scan the manual tomorrow and make it available.

Ok - this is interesting ....
This machine is missing the CPU fan - I haven't worried about it yet, because
the large heat-sink is there, and my testing has not been for long enough durations
for it to get more than slightly warm ... does the board monitor the fan tach. and
shut down if it's does not see a pulse train? Looks like this machine is completely dead - I
can't get any activity from
the video or serial ports - no beeps either.
Make sure the CPU fan is spinning. Stopping the CPU fan on my 164sx
stops the machine dead. Caused a bit if head scratching until I
noticed one of the cables rubbing against the fan.
