Haha... It may have been spelled differently, like Doo or something like that? It was an Arcade game like PacMan in those early days, not very long after Pong😎 I was already an adult when these came out...

I've got younger relatives who play-for-pay online and very little else... They seem happy enough, so I'm happy for them.

Stay well, my friend... I had Gem pop into my thoughts today for some reason...??? Might be because my friend Mr. Reddy came through my pet door again after a year and a half or so. He's been staying in my back (mud-room) sleeping - rarely going outside; looking old and tired. Has the sniffles too...might be his end days? I'll take care of him as best I can.
