No I haven't built them yet. I'm going away for a week, then after that 
I placing an order to Jameco.  But then I'll get everything I need to 
build a prototype.  I also have to program the firmware but I can do 
that before I actual order anything.

Yep, right into the link port. 

Yes I probably will build them.  But it might have to wait untill sept, 
when I go back to school.  I don't have any PC etching.  But I might 
order some with my Jameco order.


In reply to your previous email:

Each different module that you connect to the PEI will have a program to 
communicate with that module.  That prgm will tell a driver what to send 
and receive.  There also will be an on-calc interpreter that an user or 
designer can use to talk to any port.  It will be a simple basic-like 
language.  I'll get more info when I'm done designing the software.
