   Success! I have a working Pet. Lots and lots of rubbing the black pads   
   with a cotton bud dipped in isopropyl alcohol did it.   
      
   This must be the first time I have used a Pet in decades and it's a   
   really strange nostalgic experience. For example:   
      
   I'd forgotten how one has to make space to insert characters but I   
   remember how cursor movement characters show up if too many spaces are   
   inserted - similar to the effect of typing an odd number of double   
   quotes on a line.   
      
   It was really weird that keyboard shortcuts like typing L shift I as a   
   shortcut for LIST came back to me immediately as if it was more a muscle   
   memory that a mental one.   
      
   I remembered Pets being ready as soon as the phosphor glowed but I'd   
   forgotten how slow they are in Basic; characters appear on the screen as   
   if they were coming over a modem! When I was of school age a friend and   
   I wrote some machine code and were blown away with how fast it was   
   compared with the Basic programming we were used to. Speaking of which,   
   I remember, with regret, the absence of a repeat key and writing a   
   machine code routine to try to provide autorepeat - unsuccessfully, IIRC.   
      
   I took a look at the character set and I'd forgotten that some Pets -   
   like this one - had no lower case. IIRC later Pets did but I'm not sure   
   what they did with the graphics characters which they presumably   
   displaced to make the lower case chars available.   
      
   Anyway, just a few reminiscences. This has transported me back to many,   
   many years ago!
