1. Installation of the TURBO- FREEZER XL is stuck on easily at the parallel bus. The current supply takes place via the parallel bus (with the Atari 600 XL and with older Atari 800 XL) or via the soldered on cable to a Joystickport one sticks on. The Ataris or soldering work does not open equal which kind is necessary therefore. In such things however additional possibilities can build themselves experienced user with the appropriate tool. 1,1 sticking on at parallels the bus simple the caught cover in the back at the Atari remove, which sheet metal tongue with the fingers carefully a little bends upward and which Freezer without use of force put in. The cable at pin 7 of the Joystickport 2 stick on. Pin 7 is marked in the accompanying design. 1,2 first start-up The button of the switch in the Freezer to the plate center push, in order to switch the Oldrunner off (also with Freezern without Oldrunner necessarily!). The Atari alone switch on. If not after the usual short waiting period the " READY " appears message of the BAS1C, but suspicious symptoms arise (system crash, dark picture. Smoke development off immediately) and the error looks for (a Freezer without Oldrunner EPROM, but with switched on Oldrunner leads to a dark picture), is the message switches appeared, simply the red button of the Freezers presses, so that the Freezer menu appears. Nothing does, is either the Freezer badly put in, the cable not correctly attached or the Freezer got broken. Subsequently, in the Freezermenue press the space bar. Thus to the BAS1C one decreases/goes back. It tries out whether the BASIC key input accepts if it that does not do, an error is present. If up to this point everything folded, the TURBO- FREEZER XL is operational. Note: The Freezer for any reason should not correctly reference: The Freezer for any reason should function not correctly, send this back not directly, but send only once a letter with a description of the symptoms. It is impossible due to the 100%igen final test of each TURBO- FREEZER XL practical that it is because of the Freezer. It probably is at an installation error or because of the Atari itself, and it is better these possibilities by a further inquiry to exclude before the Freezer itself for examination is sent in, in order to avoid unnecessary waiting periods and costs.
