This is already posted in the sale thread so I apologize for the double post. I just wanted to make sure people are aware of the new version in case they aren't checking on the sale post.
Thesteve and I made the obey region chip easier to install. This new chip does not require that you run wires to each hucard slot pin. It fits directly on the pins for easy slim installation. Installation time is around 15 to 20 minutes (compared to previous models which could easily take an hour or more).
It wires to the SPDT as normal for home consoles with base of switch to switch soldering pad on new chip, 5v on one end of switch and ground on the other end.The switchless function for the handheld units is now on the same board but requires a couple of additional components.
The key to this install is to cut the 9 pins on hucard slot side really short.
