Teletype Model 37

The Model 37 came with many features including upper- and lowercase
letters, reverse page feed for printing charts, red and black ink and
could print 150 Baud (15 characters/second) and optional tape and punch
reader. This made it 50% faster than its predecessor the Model 33.[1]

...

The Model 37 handles all 128 ASCII code combinations.[3] It uses a
six-row removable typebox with provisions for 96 type pallet positions.
When the Shift-Out feature is included, the six-row typebox is replaced
with a seven-row typebox allowing 112 pallet positions, or it can be
replaced with an eight-row typebox allowing 128 type pallet positions.
