Built in yes, enabled by default on the 2940 (it's easy enough to check
this one, it is right in the SCSIselect menus), disabled by default
on the MC4421 (the manual is wrong, everyone of these I have seen comes
with the termination disabled).  W4 should be installed to enable termination,
just in case you don't have the manual handy.
