In October 1981, Alpha Products created a new version of their joystick which included a mode switch to allow a choice between the STICK-80 and TRISSTICK FIRE button behavior. The advertisements from then on referred to the joystick as the Alpha Joystick, and the price remained at $39.95.
In January 1981, the first advertisement for the Model III Alpha Joystick appeared. This version originally cost $49.95, ten dollars more than the Model I version. The advertisement seems to indicate that the Model III version didn’t include a mode switch. By May 1982, the price of the Model III Alpha Joystick had dropped to match the Model I joystick at $39.95.
After running a several month sale, in December 1984 the price for both Model I and III versions dropped to $27.95. They continued at that price until the joysticks disappeared from Alpha Products advertisements after November 1985.
