TSB / TRB Have Unexpected Results

[herseydj]

Hello,

When I tried to use the emulator to test some code, I noticed that the TRB opcode gave the correct test result, but it cleared bits it wasn't supposed to touch in the memory location.  The desired result was to set the zero flag based on the test of that 1 bits in the accumulator and the memory location, and clear the bits in the memory location based on the accumulators 1 bits.  The zero flag was set correctly, but the memory location also had all the bits cleared.  I've modified the two functions to split up the test and the change to memory in my local copy, and want to provide the corrected code back
