I opened up my TI-92 today and after looking at the socket for the 
RAM upgrade, I think I'd rather pay someone else to do it!  The 
socket itself is not very large and the pads for the chip leads are 
very small.  

I also was wondering if it would be possible to add more RAM via the 
ROM module socket.  This sounds possible to me if the socket has pins 
that are attached to all of the unneeded address pins instead of just 
the ones needed by the ROM chip.  I don't care that more RAM can't 
fit in the calc.  Imagine having a 1 meg SIMM in a module outside the 
calc!!!  Of course this would not be able to be used by the regular 
operating system of the TI-92, but it sure would make for a very 
quick storage module for Fargo games.
