Most PS/2 machines have it.  Only the absolute latest ones, like the 85 
and 95 don't.  It was even included in some post-PS/2 machines.  I think 
it only disappeared completely when IBM stopped using BIOS that were 
written specifically for each machine and moved to something "standardized".

They don't have the cassette port, though, of course.
