Using the turbo switch in this way makes the machine something special. You, sir, have created a truly rare breed!
Thanks, the Turbo switch does add another dimension to slowing down. I'm still figuring out exactly what it does. On this board, it affects the K6 CPUs differently, and slows down the most for CPUs with on-die cache. Moreover, other Socket 7 boards with Turbo switch also behave differently, especially ones from Intel and VIA. Both these types react to Turbo less drastically.
I would like to see this machine benchmarked by checkit as it gives Dhrystone/Whetstone scores.
For the following configuration: Baseline 1 (slowest for board), Tseng ET6100:
Is this what you are looking for? I can post more benchmarks as well - let me know if you prefer Checkit 2.1 or 3.0 for these results. I could also try the ISA Tseng ET4000AX...
CPU is slower than an 8088 at 4.77 MHz for this configuration and the FPU is significantly faster than an 8087. I'm wondering if anything used an FPU that would be speed-sensitive in this speed range?
