Get it, I may treat it as ASA 50, or the like since it is rather old. For BW developer, I have the regular T-max concentration, D-76 powder, and 4 fl. oz Rodinal. I've only used T-max developer since most of my films are T-max. The Rodinal appears very old, in its white bottle inside the orange box.
Yes, I do have dektol thought I've not used it. That is for paper.
unless it is TMAX RS don't process
sheet film in it.
regular NON RS has the potential risk of giving your film a green metalic stain / fog on your film
and the only way remove it is using farmer's reducer, and it is a real pain
using the farmer's reducer it will strip your film of density ...
yes i know dektol is (now) considered a print developer

but for a long long time it was used for FILM and PRINTS
and called a "universal developer"
and it produces very nice negatives.
i use ansco 130 for flm, have been for about 15 year+
and it is also what people consider a
paper developer,
if you are up for experimenting and having a little fun + goofing off a little bit
you could do a split process sort of thing ..
i did this a few days ago with 70+ sheets of 1983 tri x i rated it somewhere around 100, maybe less ..
you mix up some CAFFENOL C, the teaspoon recipe is fine ..
8oz water 4tsp cheap, rot gut instant coffee, 4 tsp washing soda, 1/4 tsp vit c ..
(measurements off? don't worry it is a forgiving developer, i don't even measure my ingredients )
mix up your dektol
and add 5cc dektol/8oz of caffenol c
you will dilute your dektol 1:10 and process the film in the dektol for 5 mins.
pour out the dektol + pour in the caffenol and process the film in there for 5 mins
water stop, then fix ...
i do this same routine with all my film nowadays ... but with ansco 130 ( not dektol ) ...
and instead of instant coffee i use home roasted sumatran beans ( robusta )
your film will have a nice density, contrast and not much fog, even for 31 year old film.
some of my results are attached
have fun!

ps not sure if tri x ortho is a true orthochromatic film, where it can be developed by inspection with a safelight on
like paper ... if it is, you can use any developer you want, and inspect the film as it is being developed ..
this describes how to do it with regular film
with ortho you might get the treat of using your safe light instead of the green light
