Repairing The Lynx

The Lynx needs to have a cart inserted for it to power up.

It also needs power. Either batteries (6 AA cells) or a PSU providing between 6V..9V of DC current up to 1A. It should boot with about 0.6A. Plus on the tip, minus on the barrel.

Old Lynx I units may have old batteries stuck in the battery compartment. Usually the last two batteries are stuck and the user believes that the unit is broken because he tries to replace the 4 batteries that come out, but the 2 remaining batteries are completely dead and prevent the unit from operating.

Some homebrew carts may have a sharp edge that catches a pin and folds it into the cart connection. After this the cart connection no longer works. The way to fix this is to use some kind of dentists tool - a long tool with a small needle on the end. It should be strong enough that you can bend the pin back into the correct shape. In order to prevent this from happening again you could use fine sanding paper and fix your homebrew carts to have a proper slope that won't catch the individual pins when inserting the cart.
