The version I worked with for a client was circa late 1980's. Basically it was
software that would support multi-tasking on one CPU. It was installed on an
original IBM 6 MHz AT and was fairly slow but did save the expense of another
computer by using a terminal instead. They also sold some hardware that was
basically a four-port serial card/connectors for attaching to the terminals thus
allowing multiple operations. As I said, the whole things was fairly slow then,
but worked well for something like word processing.
