> I'm thinking about a tiny, thin adaptor PCB which is first soldered to the
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.

So if there are enough of you interested in the PCB it may make sense to
develop this PCB and sell it. To get a reasonable price calculation I would
like to know how many of you are interested in that PCB and what would be
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!).
