Casio AL-1000S Desktop Calculator
The Casio AL-1000S was a follow-on to the original AL-1000, which was
Casio's first desktop programmable electronic calculator. The AL-1000S
adds the ability for the calculator to be connected to a modified
external electric typewriter to allow number and operations to be
entered from the typewriter. It is unclear if the calculator could
output results to the typewriter. The modification to the AL-1000 adds
a connector on the rear panel of the calculator. A cable connected
the calculator to a small interface box that in turn connects via another
cable to the modified typewriter. For more information about the AL-1000,

which was a Casio AL-1000 rebadged for sale by Commodore under an OEM
agreement between Commodore and Casio.
