Casio AL-1000S Desktop Calculator


Casio AL-1000S

The Casio AL-1000S was a follow-on to the original AL-1000, Casio's first programmable electronic calculator. The AL-1000S adds the ability for the calculator to be connected to a modified electric typewriter to allow numbers and operations to be entered from the typewriter, as well as for the calculator to print the content of the display register on the typewriter. The modification to the AL-1000 adds a connector on the rear panel of the calculator. A cable connects the calculator to an interface unit that in turn connects via another cable to the modified typewriter. For more information about the AL-1000, see the Old Calculator Museum's exhibit on the Commodore AL-1000, which was a Casio AL-1000 rebadged for sale by Commodore under an OEM agreement between Commodore and Casio.
