I have a Fred, I can loan it out if you think it's dumpable... Probably don't want to kill it though.

I'm pretty sure the Computerized Arcade (Tandy 12) was made in that same design by another company (I keep thinking Gakken or Tsukuda, but I can't find it there...) I know I've seen it sold by someone other than Radio Shack... Gakken made Fred, so it's possible it is there's, just the next version or something.
