Hi,

i want to run a Pentium 200Mhz Inside my PCD-5H,
Maximum CPU supported seems to be a Pentium 133.
Is it possible to handwire the Multipler on the CPU ?
Using a fine pitch wire ?

Has anyone Experience doing this ?

Thanks

Matthias

Maybe you could read a datasheet of these chips and see which pins need to be manipulated?
Another option could be to use something like a Pentium Overdrive (if you have any) or perhaps a Pentium MMX and set the multi on your board to 1.5x (the MMX chip should interpret this as 3.5x).

I don't know your board but these are my first thoughts.
