I have printed out the document but how do I work out what the pins do.
I can see that there are 8 anode pins and 6 cathode pins but that is about
as far as I get.

Hi, Roger. Driving the displays you have might not be the easiest
thing for a newbie. They work on the time multiplexing principle. If
you apply 7 bits of data to the anode pins, and then activate one of
the cathode pins, one row of the diplay will light. By using a
computer or microcontroller amd appropriate high current latching
drivers, you can scroll across the rows at a fast rate (say, 1000
times a second or so), and due to persistence of vision it will appear
that all the rows are on at once. A typical microcontroller can
easily handle this and also take care of other things such as
maintaining a communications link and taking care of other business.
But unless you've got that microcontroller, it is going to be really
difficult to get a whole lot of use out of your display.
Good luck
Chris
