Hi there

I'd buy some daughter boards with more RAM and flash for
my 14 USR2450's, happily :-)

AMD Elan CPU isn't like other SoCs with lots of things inside.

as a x86 CPU, most of the chip is dedicated to complex CISC
instruction decode. that's one of the reasons for the EOL
of this board, it became pretty expensive while compared to
ARMs and Conexants newer designs

this said, flash was already add by Tom Parker's daugher board
(http://www.wiresncode.com/projects/wireless/openap/)

a terminal (LCD) attached to serial port was done by ppl
from england (don't recall the URL, I think it is mesh
router guys). if not you can plug this ready one LK404-AT

http://www.matrixorbital.com/pages/product_view.asp?CatID=1&ProductID=11
(was http://www.matrixorbital.com/products/lk404-at.htm)

on which you can hook an AT keyboard (pricey but very
well done, this "terminal")

I've found a PC104 to dual pccard slot board, but it is
expensive and won't fit inside plastic case (yet it would
need a header to pc104 conversion so it can be pluged
on eumitcomm's board expansion slot) -- one could add
a CF microdrive and a RAM expansion on this dual pccard
slot and modify ALIOS to use that RAM instead of board's
RAM -- my guess is that it would be too much expensive
to be a viable choice to anyone

there is a new good / powerfull board, WRAP1C, with a
Geode 233 CPU, 2 LANs and 2 mini-pci card slots. it's
30-40% cheaper than cheapest soekris board (which is
ELAN 520). the next batch will be available on early
february, at http://www.pcengines.ch

Cheers
