I tweaked the clock cycle counter a little to try to get a little closer to the speed of the genuine 8088, but different benchmarks yield different results! It is possible to dial in each of the hundreds of 8088 opcodes, but I will leave that as a project for another day.
Below are a few benchmark tests, plus the 8088 MPH demo which some consider a benchmark application.
Here is the results from the DOS program MIPS.COM
Here is the Norton Utilities System Information:
Here is a screenshot of the 8088 MPH Demo. I only have 256KB of RAM on this motherboard so I believe the software skips some demos which require the full 640KB of RAM.
Here is the YouTube video of the MCL86+ running the demo: https://youtu.be/AAgtQljp0Tc
