For the additional OUT function, could you create a macro to build the instruction ? Does your assembler support that ? Must admit, John, you're getting me interested in asm again. :)

Yes and I almost made a macro for it. But z80asm is pretty lame and I plan on moving onto something fancier with a linker pretty soon. Probably also look at using C for the higher level parts. Probably be interesting to see how good a job a C compiler is at targeting the Z80 😂. -- I'd like to see how Fuzix does on this thing. And its tools include an assembler & compiler that allegedly be built for self-hosted development! Soooo....the Fuzix binutils will make an appearance before I get too far along.
