Well, it's been an eventful weekend.

I managed to discover the checksum code in the EX800 ROM. And as a
result, I was able to bypass it and then add a little of my own code
into where the Tape handling software was.

Thus, I am able to run the normal EX800 operational code and then set
the Tape Enable switch to enabled which then makes the code jump into
my own software. So far, that just means that I am able to flash the
display on and off. But hey, we are on our way.

Mike.
