Not that I normally advocate this sort of cannibalism,
but does not the
Apple ][ use 8T26 bus buffers? They certainly are more common than OSI gear.
No. Early Apple ][ used an octal bidirectional buffer whose exact part
number I've forgotten, but it was something like 8308. Later revs replaced
it with the 74LS245, which was not pin compatible. Some boards were
dual-patterned to accept either, although the socket was installed for
one, precluding the use of the other.
8T26 chips are not that hard to find. I can probably supply some
if anyone needs them, although I'll charge a premium to cover my
handling costs.
