I'm not sure how many people made, or is in the process of making it, 
but yesterday I got over 30 messages about it from people who realy 
seemed to like it. Today I posted the plans for a speaker cartridge with 
a built in transistor amplifier and a volume control. It still fits in 
the small virtual boy cases (im told that they ship them for free 
too!!!)!  (-:  There is the SF Expander cart.

I intend to make instructions SOON for converting or building future 
expanders into SPinTerface carts. I am working on an external 
SPinTerface Cartridge adaptor that would have a battery pack and several 
SPinTerface ports. It would be connected to a link cable and would plug 
into any TI calulator with a link port. There would probably be a switch 
to select which cartridge ports to be active. It would still automaticly 
power up/down when you insert/remove carts. I also am looking into 
SPinTerface "Jumper Cables." It would be a cable, about the lenth of a 
link port that would let you link two SPinTerface equiped calculators 
together. You could use it just like a standard link cable, but if the 
power of one calc is low, it would "share" power between the two. If 
your backup battery was dead and you needed to replace your batteries 
immediately, this cable would actualy be able to let a calc run with the 
batteries out (only one calc would probably run though. If you turned 
the suplying calc on, both screens would go way dim or they might not 
have enough power at all! But the idea of being able to "Jump start" a 
calculator just sounds kindof interesting.  (-:

I have an idea for an IR link, and if I get it to work, I'll make a 
SPinTerface cart for it to. Also, if you make your own cart, get me the 
design. I would like to have every possible SPinTerface cart design up 
on my page so all can see them!

Good luck!!!
