well, I did some twiddling last night with this new method and got my
pentium II 400 to operate between 3 and 5 Mhz (or so my benchmark program
said).
I played an old non-throttled game last with the machine and it was very,
very playable. I have not had the time yet to compare it against my true
8088 4.77MHz machine to see if games are more or less jerky, but I'll get to
it soon.
I found that I could get the machine to be between 26 and 3MHz in variable
steps of about 3 Mhz. eventually, I'd like to see this turned into a tiny
little program, perhaps even a TSR, that allows you to specifiy the speed
you want to run at.
I've got a lot more work to do, but this was at least a promising 1st step.
