Tell me about it. I really want a Cortex A9 *TX motherboard with DIMM
sockets. There are a few out there that sport PCI/PCIe slots, but the
closest I could find still only has soldered-on RAM (512MB) with no DIMM
sockets for increasing it. :-(
If you find some that tick that last box, I'd very much like to hear
about it. I've actually considered seeing what it would cost to get a
custom motherboard made in a small production run (say, 1,000 units),
but to do it from scratch would take a lot of R&D (expensive), and I
doubt the manufacturer of the 512MB board would consider producing a
modified version for such a small run (most ARM stuff is built in
mind-boggling volumes for the embedded market).
