I saw the Wiki XO-1.75 page was a bit out of date, as was the XO-1.75 B1
page, but I checked and they looked reasonable at the moment.  Let me
know if there's any other documentation that is lacking, or flag it with
a comment in the Wiki.

This was fixed in Sugar 0.93.2 released last Friday, but it hasn't been
included in a build yet, as far as I can tell.  Check it in the next

Hmm.  I thought it did the same on XO-1 and XO-1.5, in that it closes
the same circuit path ... and to use view source one must combine it
with the fn key.  So view source is effectively fn-space.

Yes, please test again when #11135 and #10934 say to do so.  Put your
trac username on the tickets in the CC section and you'll get a mail
when they are changed, hopefully.

Yes, #11140, and I don't expect it to change, except that once #11135
and #10934 are fixed the frame key in the top right will also work.

> The microphone and camera don't work yet.

Yes.  You will find both will work in OpenFirmware, using "test /audio"
and "test /camera" respectively.  But in Linux they do not.  This is
#10831 for the microphone, and #11129 for the camera, please test again
once they say to do so.  For the camera, you can test with os36 if you
first load the mmp-camera kernel module.

That's interesting.  More please?

Yes, #11132 and possibly others.

You tend to discover wireless problems well.  I suspect it is something
about your location.  ;-)

There's #11133 open looking for someone to test the wireless
performance, ... I suggest comparing it against XO-1.5, and measuring
bandwidth, latency, signal strength, and compatibility with access

See if you have anyone in your team who might like to explore further,
such as using iperf and other tools.

Or, just see if you can get Sugar activities to collaborate reasonably
well.  I've not tried that yet.
