[amsat-bb] Hardware

If I may impose further on the group, thanks to your assistance I am able to get Gpredict to do what I need to do, and have configured the software to match my radio and rotators. I am looking for hardware recommendations for a board that I can plug into my shack computer and use as an interface between that and my new-to-me G5500. I would welcome any thoughts or suggestions you folks might have.
