I, too, have had bad experiences with 1970s TI chips and pin corrosion. I'm
wondering if that's the problem with my Heathkit H-27 controller. No broken
pins but lots of blackened ones (silver oxides).
Four of the 5 broken chips are TI 8T26s and the fifth
is a TI 74123.

use 8T26 bus buffers? They certainly are more common than OSI gear.
