Because of the potting, I'd bet it's a "dongle" required to allow
a relatively expensive application program to run.

Is it possible for a serial card (dual port or not) to require a
dongle?  What would it need one for, it's just a serial card.  Uber
baud rates?


The dongle is not for the serial card but the (expensive) software
license.
I can imagine that it is some exotic data acquisition software,
perhaps something with an external measuring instrument.

However, I find it unusual to bundle such an expensive software
with an exotic serial card *and* a hardware dongle.

Another possibility would be some kind of processing card.
As the card isn't very large I can only come up with some
kind of number cruncher without its own memory.


I think it's just a dual synchronous serial card--perhaps to
operate a numerically controlled sign cutter or milling machine.

For such an application, the cost of the serial card and the
dongle would be negligible.

Many Apple II's were sold as a component of a turnkey application
like this.
