The

TURBO FREEZER

is simply attached to the parallel bus. The parallel bus diﬀers

between Atari XL and XE computers. In Atari XL computers the parallel bus consists of

the Parallel Bus Interface (PBI) which is labeled “Parallel Bus”. In Atari XE computers the

parallel bus consists of the cartridge port and the Enhanced Cartridge Interface (ECI) which

are labeled “Cartridge” and “Expansion”. The power supply of the

TURBO FREEZER

is taken from the parallel bus. In Atari 600 XL and older Atari 800 XL computers the

required power is available directly on the parallel bus. It is no longer available there in

new Atari 800 XL models and therefore has to be taken from the joystick port using the

power supply wire that is soldered to the freezer. Neither opening the Atari nor soldering

of any kind is required. Yet users with experience in soldering and with the appropriate

equipment have the option to add additional features.

The

TURBO FREEZER

consists of two parts, the freezer electronic in the black case

and an adapter board which establishes the connection to the PBI or ECI. The adapter

boards are available separately and hence provide a simple and cheap way to use a

TURBO FREEZER with Atari XL as well as with Atari XE computers.

There is a small number of models from the XE series (mainly 65 XE) which do not

have an ECI port. These models only have a “Cartridge” port and have no “Expansion”
