AFAIK there was the Buck Rogers semi-dedicated and then the Universal version only. Everything else in the cab that's not Buck Rogers is an op application of the Universal or BR conversion. Are there pictures that support Outrun as being a semi-dedicated or factory application and not a Universal?
I suspect the Universal came after BR since the cab has woodwork changes to fit more inline with the other Universal cabinets. Maybe BR was 1982 and Universal 1983?
Don't forget Sea Battle - it's on the flyer as a cockpit, dedicated. Some claim to have seen it back in the day so it's believed to have been made but parts have never been found
