The SPinTerface port is a 10-pin connector that can be installed on a TI 
calc that contains the connections for the serial link port, a 5v 
regulated powersupply with auto power on/off. You can build cartridges 
that plug into it or have a breadboard with a SPinTerface cable attached 
to it. If it can plug into the link port, you should be able to modify 
it to work with the SPinTerface port. Once you find the four parts 
required to build it, you will most likely never need to build another 
power circuit again. The SPinTerface replaces the need to special order 
link cables to cut up and elliminates the need to carry around a second 
box with it's own set of batteries. I designed the device and have 
installed it on two calcs already. I have had several requests for me to 
build one for people. It's realy not too difficult to build. I built 
mine in just over an hour. The second one took less time. All but the 
10-pin female connector can be purchased at Radio Shack and the 
connector should be easy to find. Try a computer store and ask for a 9 
or 25 pin serial connector with the plug that connects to the card. That 
plug is a 2 row x 5, 10-pin female connector.

My webpage is the official SPinTerface Page

Good luck!
