When I worked for the IBM APL group at Yorktown Heights in 1969,
APL\360 was running on a 360/50.  It supported several dozen users, on
a machine with less CPU capability than the 386 I have at home.  Of
course, 30K workspaces and no filesystem made that much easier.  On
the other hand, it was the only system that IBM at the time would
allow to run unattended.

I don't know if the original implementation was on that machine or a
predecessor, so the timings may have been made on a lesser 360.
