[Coco] Strange 26-3127B

[Joe Grubbs]

Sure thing Kip, I will when I get home tonight. Just external photos or the guts too?

The "Tandy" 26-3127B I have is certainly quite different looking inside than the "Radio Shack" 26-3127B. In fact, my original CoCo2 (a Korean 16K ECB 26-3136) looks identical inside to the "Radio Shack" 26-3127B   O_O

Note that this 20261043 is presumably the one for the Korean 26-3134/3136 16K CoCo2 according to my Googling. However it is 64K and has Tandy house-marked memory ICs (8) as well as what looks like a perfectly installed jumper in J1. It goes without saying that it merely has the 6847 VDG. In all of my web searching, I've not found mention of a similarly configured 3127B, though one site stated that the 3127Bs were a bit varied.
