Ok. but not always usually.

No problem!
Checkit is not true indictor of performance, it's so easy on CPU so
it get fooled by the emulator than other way around. Very general
check to make sure things works and meet clocking rating.
Right now I'm using this checkit 3.0 to debug a motherboard because I
am trying to get it into turbo mode by keyboard, It's Nec Powermate
386 33i (386dx 33 cached all in one board). What is the key combo
to enable turbo? It's Phoenix bios. Currently I got it bare from
susplus for 5 dollars then plugged cpu and memory to it. Made up
both keyboard and the power supply adapters. Got speaker, hard
drive light and the 5v, grounds all traced out along with that 14pin
header that also connects to keyboard. Not yet to find out the
power/speed light. Any takers on this info or comments how this
design is done? BTW tried bi color two leaded LED for this with no
luck. Did this 14 pin header also carry PS/2 mouse signals too?

Oh man 386dx 25 is too popular already, I have several along with AMD
386 40 (couple) and slow 386/387-20 as well.
Also to point this way of cost of getting 486's are now cheap as
pennies: I have 486sx 33 and one dx2 66 but no good board yet!
Also lot of pentium 60/66, and 75 are cheap now.
