Looking at the archives it is clear that this has been noticed<br class="">before, but then I came across this message which indicates that there *is*<br class="">likely an older datasheet with extra charts which are not to be found on the<br class="">usual one:<br class=""><a href="http://search.retrosynth.com/synth-diy/search/lookit.cgi?-v9902.413" class="">http://search.retrosynth.com/synth-diy/search/lookit.cgi?-v9902.413</a><br class=""><br class="">This reply to that post specifically mentions charts which apparently don't<br class="">correspond to any on the usual datasheet found online:<br class="">http://search.retrosynth.com/synth-diy/search/lookit.cgi?-v9902.419<br class="">(Is Terry Michaels still around?)<br class=""><br class="">I found a large collection of old Fairchild databooks here:<br class="">https://www.rsp-italy.it/Electronics/Databooks/Fairchild/index.htm<br class=""><br class="">and searching through those only turns up the usual 'cut-down' version, the<br class="">oldest being from 1973. Frustratingly the 1969 databook, which lists the<br class="">uA726 in the contents as being in chapter *6*, only goes up to chapter 5, so<br class="">this _might_ be a candidate for containing the older data..?<br class=""><br class="">Does anyone here have a really old databook with the uA726 in it which<br class="">contains the 'missing data', or an older copy of the actual datasheet, which<br class="">could be scanned and made available to the masses?
