LZ: Anyone (successfully) used the EXX



-> I was trying out some new routines for the expander, and it would
-> really help if I could use the register exchange command.  However, I
-> remember trying it before, and it didn't work.  Has anyone used the
-> EXX command?  I'm wondering whether the processor in the TI-85 is a
-> "true" Z80 or whether the custom design they used left out the
-> alternate register set...


It works, but since it is used by the TI-85s main Interrupt you lose
your registers.
