John,
There are four kinds of Tri-X. There's PROFESSIONAL Tri-X 320, Film Code
320TXP, with an ASA/ISO/EI of 320/640. Then there's Tri-X Pan Professional,
Film Code TXP, ASA/ISO/EI 320/640. And there's PROFESSIONAL Tri-X 400, Film
Code 400TX, ASA/ISO/EI 400/800. Finally, there's Tri-X Pan, Film Code TX,
ASA/ISO/EI 400/800.
Develop any of them for about 8 minutes or so in D-76 and you'll end up with
something usable, maybe a little grainy, depending on what you expect, but
good. Tri-X is my second favorite B&W film, right behind Plus-X, of which
there are only three kinds. :-)
