[Coco] tandy 512k board and the triad board

[Josh Harper]

 hi guys
I have a coco 3 with a tandy 512k board in it, is there any good reason that I should replace it with a triad 512k board
is it as simply as pulling the tandy board out and pluging the triad board in
also is there any games  that will only run on a coco3 with a 6309 cpu
also how can I find out if a 26-3024  and a 26-3124 multi pak has  the coco 3 upgrade without opening it
thanks
