When doing this, I discovered that everything that's written to $2400
shows up at $2000, same with $2c00/$2800, $3400/3000 and $3c00/$3800.
Looks like A10 is always low. Visual inspection and a bit of prodding
shows that the pin doesn't make full contact.
Sounds like we have a winner, thanks.
PS: I expanded the memory test program to incorporate address bus
testing.
