I was going through some old boxes in the storage loft (you wouldn't believe all the stuff up there) and found all of the versions of the BDS dating as far back as 1995, when the name "BDS" was first used with Remote Audio's first product. So, I mounted them alongside the current version for a "family tree" photo.
Another bit of historical trivia: "BDS" has always been the trademark of this Remote Audio product, even though it's flattering that people use the name like Jello.
