---+!! Introduction

%TOC%

I dissassembled my iFP599 and made careful notes.  I'm leaving those notes here just in case someone finds them useful.  (Who knows, there might be enough interest to start a RockBox port.. sometime in the future.. please?)

Someone on MisticRiver noted iFP3xx and iFP5xx devices are similar in many respects, while iFP7xx/8xx use a newer microprocessor (PhilipsPNX0101).  The ifp-driver mailing list noted the newer models seem to have less processor power.  

LinusNielsenFeltzing: This looks really promising! Would it be possible for you to produce high-res scans of the circuit boards?

GeoffOakham: sure.. just mail me a scanner and I'll post them right away!  Meanwhile, I have these pictures from a digital camera.. does that help? 

LinusNielsenFeltzing: The biggest problem is to find the data sheets for the SAA7750 microcontroller. They are not public, so we'll have to dig deep.

GeoffOakham: I've asked Philips for reference material, and they've acknowledged the request.  I'll get back to you when they do.
