ColecoVision Expansion Module #3 The ColecoVision Expansion Module #3 is an add-on that turns the ColecoVision game console into a Coleco ADAM computer system. It consists of a Memory Console, keyboard, and ADAM printer. There are a few differences between the #3 Memory Console and the normal ADAM Memory Console, mainly the fact that the #3 lacks the cartridge port and reset switch the ADAM's has since the port is already present on the ColecoVision. There is also an expansion port on the rear of the #3 which the ADAM lacks, as this is where it plugs up to the ColecoVision. Otherwise they are very similar in appearance and capabilities.
