      If you have binaries of a z-80 capable MBASIC I'd love to grab a copy. I wrote an Altair emulator a while back that used a Z-80 library under the hood. I had to modify it to fix the flags register in order to run the copy of BASIC I had (one of the few incompatibilities of the Z80). I'd love to compare the two to see what they changed to fix it.

      http://altair.csquare.ca if you wanted to play with the emulator :)
