thanks for all your great suggestions - and sorry for not having
answered you sooner ...
let me share some more info on the subject ...
for one project we will go with standard mini-itx mainboards and a
heating in the case - and of course with ssd instead of hdd ...
for the other one i found a really nice device from germany calla MoRoS:
despite the fact that this is fully linux powered and has tons of nice
features (gsm/grps/umts, rs232, 4xethernet) - the *main* feature for me
is that you can upload a so called "sandbox" image with your own linux
programs - supported by denx eldk ... its arm based, but i have not got
more detailed spec about the internals until now ...
i know this is not really "embedded" the gentoo way
- but i think
this could be well suited for some nice hacked up projects
the other interesting thing i found is the fit-pc from compulab.co.il.
has any of you any experiences with this device ?
basically this is a very low power (6-8 watts) atom platform - according
to information i got from compulab the boards are also available in -20
to 70 and -40 to 85° - but only for 100+ pieces and you have to buy a
development board also - which is in the range of about $800.
the complete fit-pc (atom 1.6 ghz, 1gb ram, wlan but no hdd) is about
255eur here in austria ... and is certified from 0 to 70° ...
i will take a closer look at the igep's now ...
regards and all the best from austria,
