I'm going to guess that you've stripped the E3 control from a Bridgeport
and are now retrofitting with the STG and EMC. For a description of a
similar machine see:

To answer your question more directly, you'll want to hook each switch
up like this:

+5Volts(from PC)--/\/\/\/--STG Input--NC

and

C--Gnd

The resistor can be anywhere from 100ohms to 10k ohms, but I'd stay 1k
ohms or lower.

If you'd like to come over and see a machine with this hookup, you're
welcome to stop by if you're anywhere near Baltimore. If you'd like to
talk about this by phone, don't hesitate to call.
