This article is an adjunct to the schematic produced from the reverse engineering. Some references and descriptions may not make much sense without reference to the schematic. A simulation of the AL-1000 has also been completed and can be used to observe the execution of the procedures described in this article.
The AL-1000 dates from the late 1960s. It provides the basic four arithmetic functions and square root. Simple straight-line programs of up to 30 steps can be stored and executed by the AL-1000. It utilises more than 400 discrete transistors, over 1500 diodes, Nixie tubes for the display, and core memory for number and program storage.
The AL-1000 was also sold under the Commodore label.
