I may have found a problem with entering numbers in hex mode. I can't seem to enter a value of 'E' as the only (or the last--least significant) digit. I have tried in Unsigned, 1's Complement and 2's Complement. I can enter all other values but 'E' returns a 0 as the only digit and is eliminated as the last digit.
I am currently working with the emulator and not the real hardware.
Cheers,
Marwan
