PROFS the
IBM program was also known as
NOSS. It is a horrible green screened terminal based system. It was still in use up to about 4 or 5 years ago. But then when I worked for
IBM (UK) back then they still used
OS/2 Warp (version 3.0) as the standard desktop environment.
Oh how the US Interns laughed as they booted up their Windows 95 laptops. OS/2 really makes Windows look perfect.
