Going through my man cave today and found 6 boxes Ilford fp4 2x3 dated 1993 and 1995Speed is 125, going to shoot some for fun. Should I increase the development time (d-76) if so how much or expose lomger,or just pitch it.

Perfect opportunity to conduct some testing! Shoot 2-3 carefully metered shots at the nominal ASA rating, develop per usual, and adjust accordingly. I wouldn't "pitch it" unless the stuff is definitely unusable! As you probably know, they aren't making 2x3 negative stock anymore.

I strongly recommend HC110 dilution B or unofficial dilution H @ 65F and a 15% to 25% increase in developing time.
As Henry said testing is in order.
It will have a high base fog and lower development temperature helps to reduce it. Although its a ISO 125 film EI 25 or EI 50 will be necessary to get usable images.

I find this to be true also for my favorite B/W negative film, Ilford XP2Super. Actually a C-41 (chromogenic B/W, i.e., color negative chemistry) formulation rated at a nominal ISO 400, it requires ISO 100 to produce usable negatives for me, for scanning into Photoshop. Also, I don't have to develop the film myself!

*based on some 35mm TriX from the mid 1980's.
There is currently some discussion on 1963 Pan X on photo.net B&W Film and Processing section. Probably worth looking at.
