Since it has a -38 (not -38A) Shifter, and what I'm hoping for is a short-top border GLUE, I traded a fully working 1040STFM for it today.
(I'm surprised to see it has a 1MB piggyback, but from the looks of it I'm not sure it was done by Atari)
Besides the obviously very fried serial chip, there's a nick to the mainboard capacitor that might or might not be relevant. I'll not be able to do much investigation until a week from now, just posting these pictures up here to document the start of the journey.
