Re: [iPAQ] Cpu scaling ??

Bob,

Thanks for the offer.

I think SDRAM is between the two boards, but I don't have one in front
of me. I disconnect the touchscreen (narrow flex cable) to get these
apart, but I've always been afraid to disconnect the LCD connector.
This connector and cable are very fragile.

Start by fetching the specs for the parts I named below from the Samsung
website.
