HP38G, HP39G & HP40G Serial Interface Cable Pinouts

Making a cable is NOT simple because the distances between the pins is non standard. I've been told that the spacings are correct for some hard disk connectors but I can't verify this because I've never tried to make a cable myself.


The first four pins are used for serial rs232 communication, the later pins are used for the display connection when the cable
is used to hook up to an LCD overhead display.
