I have found a possible source of the flash memory chips!
I got hold of a 128MB Lexar Memory Stick (not duo or pro, just a regular one), it's in a transparent purple case so you can see the chip inside. It says
there seems to be a supplier here (or so they claim): http://www.partminer.com/pagedetail/5353/18
I am willing to sacrifice this memory stick and extract the memory device... and to try and solder it into my 6000. When this subject first got discussed and I got all excited, I found someone with surface mount tools, so maybe I can resurrect this plan!
would anyone find a photo useful?
--edit: oops, it was 334 and not 324 and also added supplier
