Developer: Tom Calderwood

Tom Calderwood was one of three programmers, with Mark Ackerman and Glen Parker, on the Atari 2600 version of Galaxian, released by Atari in 1983. The conversion was programmed at General Computer Corporation. It is known for putting more objects side by side than the console normally allows, using a timing trick that Ackerman patented.
