Hi all,
I'm trying to configure a MartyPC box which performs like an 8088 at 8 MHz but can't make it work. It's either 4.77 MHz or something above that via the turbo button. I appreciate any insight.
Turbo should be 7.3MHz. In what way are you seeing it way above that?

I'm using the ibm5160_xtide config.
Without turbo, Topbench scores 4 and classifies the box as an Intel 8088 @ 4.77 MHz.
With turbo, the box scores 13 as an NEC V3 @ 8MHz.

That's not incredibly far off the mark, although I'm not sure why it's picking up an NEC for that. Do we have results to compare to from a real 8MHz system?

FWIW turbo is upwards of 14 MHz for me.
