So I've been waiting for the 1400 series B-B version because, well it's really the only game in my locale in my era, but with the announcement is a wrench... they're doing the 1430-1444 series. These were converted from rebuilt A1A 1600 series units in the late 90's, ten years too late for me. So I ask, why the former 1600 series units? Is there a difference between the original 1400's and the converted 1600's? I'm guess there is but have to ask.
