Hi Chuck
If you are not sure of the polarity of the socket,
you can power up with the part removed. This way you
can check the power leads. As I recall, most of the
Dallas parts have 5 volts on the highest numbered
pin and gound at the other corner.
If you are putting a new clock in, you may need to
cause the clock to start. Most are shipped in a disabled
mode and require a write to one of the control registers
to start them. Check a Dallas spec sheet.

Can anyone tell me where pin one of the DALLAS real

should point when installed on a 4000/60 main board ? This is the leading
culprit in my dead 4000/60 but I'm not sure I recall how to place it back,
and while it seems like the socket indicates one way, its not clear that is
the correct way. Thanks,
