<div>Hi, I'm Uwe.<br />
<br />
I am a researcher and lecturer in electronics at Uppsala University in Sweden and have been interested in electronics forever. Gradually from just being a hobby it became also most of my professional work. My home and office are stuffed with modern and vintage electronics parts which from time to time come in handy in a student project or when fixing broken equipment in our research labs.</div>Uwezihttps://en.wikichip.org/w/index.php?title=User_talk:David&diff=39158User talk:David2017-02-28T12:04:06Z<p>Uwezi: just a minor comment</p>

<div>==reintroducing sidebar menu==<br />
Hi I see you've been trying to fix the sidebar extension so that it works for 1.25. If you need any help I can provide assistance! --[[User:Jon|<font color="green" size="2px">Jonathan</font>]] ([[User talk:Jon|<font color="blue" size="2px">talk</font>]]) 12:31, 14 November 2015 (EST)<br />
:I've got it covered for now, thanks! I think I'll upload the source to githup seeing how the extension has not been maintained for 1.24+. Might be useful for other wikis. --[[User:David|David]] ([[User talk:David|talk]]) 17:04, 16 November 2015 (EST)<br />

==Who are we?==<br />
Hi David, how long has this site been around without me noticing it? I found it today when googling for an old chip I found in a drawer at work, the MB8855. I have previously been involved in the ChipDir-project which seems to have faded away, as well as in the HardwareBook. I will come back here and dump a lot of missing info I guess! --[[User:Uwezi|Uwezi]] ([[User talk:Uwezi|talk]]) 07:03, 28 February 2017 (EST)</div>Uwezihttps://en.wikichip.org/w/index.php?title=fujitsu/mb8850&diff=39157fujitsu/mb88502017-02-28T11:46:35Z<p>Uwezi: added a photo</p>
