[Arm-netbook] Question about resolution on the micro-desktop

I think there was another discussed solution not requiring "anything" (not
even line buffer upscaler IC) on the housing. Namely just drawing the small
resolution directly to the higher-resolution display to the edge where the
signal starts drawing the first line). Did you abandon it? If yes, then why?

Well, in the spec on
http://elinux.org/Embedded_Open_Modular_Architecture/EOMA68/Hardware it
says for PCMCIAv2 and PCMCIAv3 "maximum RGB/TTL resolution permitted is
1366 x 768" which clearly disallows any negotiation. Could you please
correct these statements on the wiki page?

Also, if all the housings must support the rates of 1366x768, then I would
say it's too much. One can find devices like small netbooks or tablets or
special-purpose devices like projectors, but mainly TVs with resolutions
starting at 704x240 at 60 (704x480 at 30). For all these mass production will
continue for at least the next few years. During these years EOMA HW should
spread also to these domains.

 doesn't have to be amphenol.  any mass-volume connector will do.

Any tips for other 45-70 pins connectors with physical size similar to
PCMCIA and being suitable for a possible high-end EOMA spec (maybe
utilizing PCI Express link(s) instead of one of the USBs in EOMA68, maybe
MIPI DSI instead of RGB/TTL, maybe 18W dissipation like the lowest MXM,
etc.)? On http://elinux.org/Embedded_Open_Modular_Architecture there is no
such connector. Something like M2 for "big computing" (i.e. made physically
robust (incl. full coating) and freed from stuff like ADC pins, 10 GND
pins, etc.). What caught my eye is, that M2 actually does not limit thermal
dissipation at all.

You tried to contact many manufacturers and companies. Did you happen to
contact also M2 creators?

By the way, could you ask administrators of elinux.org to set up either
mod_rewrite in Apache (or equivalent in nginx or whatever server they use)
or at least disallow/blacklist pages with traling slash in their name?

Currently if one goes to
http://elinux.org/Embedded_Open_Modular_Architecture/ , it's empty, but
removing the trailing slash gets one to the correct page. This is very
confusing (see https://phabricator.wikimedia.org/T14703 and
https://bugzilla.mozilla.org/show_bug.cgi?id=961132 ) and therefore e.g.
wikipedia is also redirecting to a page without slash (try e.g.
https://en.wikipedia.org/wiki/Main_Page/ ).

Kind regards,
