This is because the limit command is built-in to the shell (csh).
You won't find it in its own manual entry, but under 'man csh'.
That is also why 'whereis' doesn't find it.
Unfortunately, without reading the manual entry for csh entirely,
one cannot apriori know if a command is built-in or not.

There is a master index in the Ultrix manuals, and fortunately it does
show the built-in commands in their own right.

I believe the only way to find how much physical memory you have is to
watch it when it boots up or look in the error log file for the
boot message entry:

ultrix: uerf -r 300

watch it when it boots up or
