Do you have the necessary facilities available to you to desolder the EPROM?
If so, what about the facilities necessary to read it?  If you do, great, 
else you could send the computer (or desoldered EPROM if you can get that
far) to either Dave Lawson or myself, where we both have the necessary
equipment to desolder and read what's inside that EPROM without any worry
of damage to the computer.  As Dave mentioned, we've both dumped our stock
TQC code and dissassembled it, so we have a good idea of what's going on 
inside the stock chip.  Another data point would be a big help!
