You didn't go quite far enough back in the old
"way back" machine.

The legacy machine for all that we currently work on started
out waaaay back in 1971 on the System/3. This was the beginning
of what we all call the "midrange" systems.

With very little or no changes, many of the programs written for
the System/3 could be run on the current box.
