Trace86 2.x

Advanced Trace86 is a full screen debugger tool that lets users visually trace through execution of 8086 machine code.

It may have been the first IBM PC machine code debugger to show execution visually. Most early debuggers were console-based and intended to be used via terminals. The interactive visual capability was also welcomed as a potential educational tool. One could step through individual instructions, or set breakpoints to jump over loops and subroutines.
