IPL Initial Program Load translates IDIAC source text programs to machine code loaded in memory and displays trace of next instruction at location 0 and displays all of non-zero memory along with any assigned assembly code labels.
RUN executes up to 10 million instructions and displays last 10 instructions, register, condition code, and all of memory, The limits for RUN unit instructions and trace entries can be changed via GUI input fields. The emulator runs at over 50 MIPS on an Intel i7 core processor on Windows 10 PC.
