Apple II

I've been using this monitor for years, but just became curious about it's label with 'For Apple Use Only', yellow sticker dot, 'apple service', ser. # and some other identifier  in pen ink - all underneith the lable's lamination.  I was able to find one other image of a yellow dot on the rear of one of these monitors.  At one point, I had a G4 Cube that was labled on the insidc 'Apple Test Machine' and am curious if this is something akin to that or...  just something normal.  Certainly doesn't seem so to this brain.  But let's hear from the experts of 'yall out there.  =]

I bought a vintage Apple IIe for $300 in August.

 But the Esc key was broken. It wasn't that the keycap was missing, but the switch was broken at all.

I was going to buy a key switch on eBay. But I heard somewhere that the height of the switch varies depending on the location of the switch. I don't know what to buy.

And yesterday I accidentally broke the left arrow key too :/

(sorry  about bad english)

Another public service announcement.  I've been refurbishing a lot of Apple IIc's lately and they all have a lot of screwdriver/tool marks around the case where people were poking and prodding and levering (and therefore damaging) their case to open up their Apple IIc cases.  iFixIt page is wrong, don't listen to them.  Stop it people!  There's an easier, tool-free way to instantly pop open your Apple IIc case:

Open the handle, lift up the back of the unit 6", and drop it.

Hi!  I have a cc65 UI library called Fields.  It provides a way to perform data entry and has menu support.  It has versions for some CBM targets and the Apple2enh.  You can find it at https://sourceforge.net/projects/cc65extra/files/ui/.  It doesn't handle my memory enhancements but should work in systems containing these.  Unfortunately, it doesn't, and I can't figure out why.  I'm asking for help with these.
