Removing the plexiglass cover reveals the bulbs and a pair of switches,
which are used to set the clock.
The bulbs are GE/Sylvania type 53, which are the bayonet style (push and twist to
insert or remove).
The display is organized into five columns.
The two rightmost columns represent seconds; the rightmost column is the onesposition
and the column to its left is the tensposition. The rightmost column counts the seconds from zero to
nine in binary (least significant bit at the top) while the column to its left counts the
tensofseconds from zero to five.
The next two columns represent minutes in a manner identical to the seconds.
The center column is the onesposition
and the column to its left is the tensposition. The center column counts the minutes from zero to
nine in binary (least significant bit at the top) while the column to its left counts the
tensofminutes from zero to five.
The leftmost column is the hours, which counts from zero to eleven in binary.
