The ref did specify it as TTL, so yes, bipolar.

FWIW, 27S82 is listed in the 1982 IC Master as
AM27S82M: TTL 1024*8 ROM, 275nS access,
OC outputs, 24 pin, 5V supply
So half the size of a 2716.
The book lists PROMs and ROMs separately, so it was probably mask-programmed.
(M would be for mil temp going by other AMD numbers.)
I would think bipolar PROM since rest of the AMD 27S series were bipolar PROMs. I will
check this weekend if I can find an old AMD databook.
