As for the Tri-X processing hasn't much changed for it
for years. Data sheets for the "old" Tri-X are still on the
Kodak web site. Old film tends to become foggy. If its not
exposed film expose it at about half the ISO speed and
process normally. If its exposed give it normal processing.
Film pack Tri-X is the same emulsion as used on roll Tri-X.
A starting point is D-76, undiluted: 8 minutes @ 68F,
small tank agitation or 7 minutes in a tray with constant
agitation.
Film packs are very simple, just pull the tab and tear
it off. The first tab is a "dark slide". Pulling that will
uncover the first film. After that you must use the
adaptor's dark slide. After making an exposure pull the next
tab to bring the next film around to the front of the film
pack. Film pack film is on a thin support much like roll
film. Film packs were very commonly used on cameras designed
for glass plates. I don't remember when Kodak discontinued
them but its been more than a decade.
