The big difference between SVR2 and SVR2.1 for the 3B2 is that the latter
supports paging (as opposed to swapping).  This is typically a big win.

Apparently, the software you are running was compiled with an old issue of
the C compiler.  a.out files created by that compiler will not run on a
3B2/300 with a paging O.S., although they are supposed to run on any of
the 3B2 systems based on the WE32100.  As I recall, there's a problem with
the WE32000 chip fixed in the WE32100 and worked-around in later versions
of the C compiler.  I seem to remember this all being documented somewhere.

Looks like your choices are to go back to the software vendor or upgrade
to a 3B2/310.  Have fun.
