archos PCB instead of the original DRAM chip and second the 8MB DRAM is
soldered onto it. Only the two missing address lines have to be wired then
instead of all the control lines and stuff.

the maximum price you would pay for it (excluding shipping/customs duty

will issue the results of this survey to this list end of February. Until
then I should have decided on the final order/payment procedure (suggestions
are very welcome!).
