Do you have an expander or an expander chip. I am getting two. I normaly 
would not sell it, but if you can't find one on your own to send to me 
and put into an Expander cart, I might be willing to sellmine. It 
dependes on if I have enough memory left on the one I keep. Chances are 
that I'll keep both, but if Mel Doesn't have anymore (you can ask him) 
and no one will sell you one (put a "want add" into TI-H), and if I feel 
certain I have enough memory on one chip, I could possibly sell it to 
you. It's a 1 Meg chip.

I can still do the SPinTerface and the temp sensor, etc. How many ports 
do you want/need on a SPinTerface port strip. $20 for 2 and $5 for 
additional ones.

It won't be for a while, but I want to create a cart with an expander, 
an 1/8-bit sound interface, and a temp meter. If someone comes up with a 
working design, I'd add a clock or anything else. I can't do the 
programming, but it would use I2C, and I KNOW that I2C works. It may 
require its own batteries, because if it's too big, it could cause 
problems, but I think a simple one can be built with the SPinTerface 
power supply and not EAT current. Who wants an A/D D/A converter for lab 
or class use or stuff like that.

The only thing is that I wan't it to interface trough I2C. You can use 
multiple devices with it and they don't interfere with link opperations, 
making a through link port possible. If I do this, It will take time, 
but I think it would be worth it to combine all those things together.

I will install a SPinTerface on your calc if you still want it. I can do 
the temp meter, sound cart, multi port cart strip, and the expander if 
you provide the chip. If you can't provide the chip, and I'm sure I 
won't need mine, then I could build an SF Expander cart for $40. If you 
get an expander II or III later on, I will do conversions into 
SPinTerface carts. I think I can make relatively small carts that will 
be very easy to handle.

Someone said they were working on a joystick. If they finnish, I'll get 
the design and see if it can't be made to run the arrow keys or as a 
variable position joystick, selectable by software???

Ideas are welcome!   (:

Hope you get your Expander chip!!!
