This is a post about buttons with square rims. But it's also a story about my very first self-built control panel.

When I was a young'un, back in
1988, I had the home version of "Track n Field" for my Commodore 64. It came with a nifty blue plastic controller with the same button layout as the arcade. It was better than wiggling a joystick side to side, but the buttons were CHEAP. I was unsatisfied.
I had the idea of building my own control panel (yes folks! 1988 is when this sort of hobby first hit me!) So I wrote a letter to Wico, whom I felt made the best joysticks of the time (Command Control!). I asked them if it was possible to order one 9-pin plug/wire like they use in their joysticks, and 3 arcade buttons.
Well, nice company they were back then, instead of returning a letter saying "yes you can, here's our catalog", they sent me merchandise free of charge! (plus a catalog and a credit application). I guess they didn't realize I was just some kid.
Anyways, so I got 3 or 4 buttons, and the joystick plug. The button colors didn't match, because I guess they were meant to be samples. I got 1 light blue, and 2 translucent reds. But get this, one of the red buttons had a SQUARE rim/lip! Otherwise it was a regular leaf-switch button, but the rim was square! Now, I originally was posting this thread to ask if anyone has ever seen these? I never saw any game with one, so perhaps this was a short-lived product that Wico introduced.
To finish up the story, I got a small piece of wood and had my dad drill the holes for me. I nailed a couple little blocks on either side of the panel to prop it up. Hooked the buttons up to my Wico 9-pin plug (compatible with C64, Atari 2600, etc) and voila, I had my own Track n Field controller with real arcade buttons. (It worked great with other games like Decathlon too).
I wish I still had it or the buttons so I could document it on my web site, but I don't. I'm still really curious about that square rimmed button though.
