TPF itself, and the programs written in it are mainly in s/360 asm, so I doubt very much it's running on x86 now. It's so s/360 it doesn't have traditional stacks.

Is there a way to reconcile these two above responses? They seem to be very different answers. Are these both options that a customer can choose from?

Yeah, it sounds like they rewrote it piece by piece to run on different architectures.

Really similar to having a big monolith, and taking pieces out chunk by chunk rewritten to run as microservices until you're left with a new codebase with no sign of the original monolith or any of it's code.
