Ice,

Thanks for your suggestion. I'll give it a shot ASAP. I used to play a lot
with serial and parallel cables a lot back in the day.

Thanks!

Rick

On the cable question:

Magellan (Thales) claims to accept queries on its old units. Have you
tried
to get a pinout description from them, and maybe you can fashion your own
cable. But you do have to register...
