OK, I have no idea if I'm doing this right.

I'm trying to get the value of IO port 02h and put it into AX. So far this is what I have, based on some other code on that @M0CUV wrote. My gut says that it's not right.

For full context, this is for an ASIC9-based machine (NEC V30H or V30MX, so 8086 plus a few extra opcodes). Port 02h has some info about these machines that the emulator dev needs to get info on memory mapping/addressing/mirroring.

I'm hoping this little bit of code that I'm going to throw into is going to give me the value of IO port 0x02 on an ASIC9-based Psion. 4.1 doesn't hate it, so I just need to try running it on a real machine. But that's a tomorrow problem.
