These are pictures of the computer room on the third floor of the main
bank building in about 1980. The computers require more air conditioning
than the building's cooling system can provide so the computer room
has extra chillers designed specifically for that purpose.
On this particular day a new A/C unit was being added in preperation
of more computer equipment. The A/C units were too large to come up
via the elevators so the windows were removed from the Congress Ave.
side of the building so they could be lifted by crane from the street
into the building.Page: 1
The new A/C unit, seen in the background, has been hoisted through the
windows and workmen are replacing the glass while a Burroughs field
engineer inspects the computer's diskpack storage units. The taller
boxes were called "225s" and the shorter ones are the "206s".
A view of one of the main computer consoles and one of the two
Burroughs B-3800 mainframes, this one referred to as "West" since it
sat on the west side of the room. There was also an "East" and, later,
a "North". In back are the 5N (short for 5 nanosecond) Head-Per-Track
disks and another A/C unit.
Another view of a glazier replacing one of the windows on the west
side of the building. Also pictured are various pieces of hardware
such as printers, card readers, tape drives, etc.
This is the south wall of the computer room, showing off two cabinets
that consisted of the all the networking hardware at that time. Eventually
the network grew to require an entire room but in 1980 it was
