ALGOL-68 is out
ALGOL, i.e. -60, was never in: and they're very much different.
However an interesting question is whether The Unisys (nee Burroughs) implementations of ALGOL hew to the -60 or -68 language: I've got limited time to delve into the manuals right now.
I was, however, looking at a 1970ish Burroughs ALGOL compiler a couple of days ago and noticed that they'd not adopted a trivial tweak to the language to eliminate the notorious "dangling else" issue: and that tweak was published by the CACM as "Revised Report on the Algorithmic Language ALGOL 60" in 1963.
So extrapolating from that unfortunate example I'd expect them to still be using ALGOL-60 "warts and all", and a very quick perusal of their ALGOL manual dated 2023 appears to confirm that.

with their systems programming language NEWP being structurally similar.
So while ALGOL-68 remains of broad interest to language history nerds, only its influence- on Ada, PL/SQL and so on- is really relevant.
