  4. New OVL with bank overflow handling on READ. 

    Add 8080 CPU testers. CPUTEST and especially 8080EXM take very long! But
all four pass succesfully.

  1. New version with proper message when an undefined opcode is encountered. 

    For example, if you try to run Z80 code or STAT.COM from CP/M-65 instead
of the 8080 version.

  1. 8080.ovl core, slightly smaller. 8080 zero page vectors are set in main 

    program. No need to set them during load.

  1. New 8080 core for the Master 128/512 which eliminates all writes to $f4 

    for MOS because it restores 'curbank' after each syscall.
