If they are all running ksh93 both of these methods *should* work:
$ ksh --version
$ print ${.sh.version}
They did on the test systems I have access to (FreeBSD, NetBSD,
Solaris, and UnixWare) running various versions of ksh93 r, t, and u.

To the best of my knowledge there are two ways to determine the
version of ksh88:
1. run what(1) on the ksh binary (binary name depends on vendor):
$ what /usr/bin/ksh | grep Version ## Solaris
$ what /usr/bin/ksh88 | grep Version ## UnixWare
Solaris up through version 9 at least installs ksh88 as /usr/bin/ksh.
If CDE is installed, /usr/dt/bin/dtksh is an ancient ksh93d, otherwise
no ksh93 is provided.
UnixWare installs ksh88 as /usr/bin/ksh88; /usr/bin/ksh is ksh93.
dtksh doesn't support the "--version" argument but does support
"print ${.sh.version}", at least on Solaris and UnixWare.
2. Start ksh88 then type:
"set -o emacs" then "ctrl-v"
--OR--
"set -o vi" then "ESC ctrl-v"
