@tbn97 CoCo2b's (cat 26-3127B)have a 6847T1 VDG that supports true lowercase with a POKE. You can tell 2b's by typing the number zero on the machine. If the 0 has a slash through it then it's a 2b. If it's a hollow zero then it's a normal 2 with the original 6847 chip.
Also 2b's say TANDY on them instead of Radio Shack.
See here for a good summery of all the coco2 models
