Notes::

This product is a printing version of the -45A.  Printing was in red
and black.  May be the same unit as the -81A but with different ROMs
and labels.

The LED display was optional for $100.  Information on the optional
display is in []s above.

The product could be field-configured for either 110V, 120V, 220V, or
240V operation.

The first (top) row of keys was narrow rectangles.  They latched down.
All other keys are standard computer/electric typewriter style.
Numeric keypad keys are white, right hand block of 10 are creamy
yellow, all others are dark grey.

The manual included key sequences and displays to verify proper
operation.
