LOL. We could also go back to CompuServe, which was accessible by dumb
terminals (and IIRC ran on PDP-10s), and others like it.

I once read that the CompuServe username mapped to a PDP directory name.
Any truth to that?

Probably, in a way. Compuserve ran PDP-10s, with their own OS, which was based on TOPS-10. The "username" was the PPN, which is the TOPS-10 equivalent of the UIC in VMS.
It was pretty normal in TOPS-10 to have your "home" directory to be the same as your PPN (if not required), but since Compuserve hacked things a lot, who knows what, if any mapping, was used in their OS.

(Btw, PPN stands for Project, Programmer Number)
