This post at InstaPundit took me to Gizmodo, who in turn linked to Pocket Calculator Show, who happened to have a boombox museum.

Back in my high school days I used to be the obnoxious guy at the back of the band bus with one of these:

…picture of a Magnavox D8443 aka the “Spatial Stereo Power Player.” This was probably the most ambitious release of Maganavox ever, featuring 5 Speakers, 3 Amps, SW tuning, Mic, Line In/Out via RCA jacks and a “Stereo” control which goes from Mono to Spatial. The system is quite large: 13” high, nearly 2 feet in length.

Did I mention that it was quite loud?  And that I played Run-DMC and L.L. Cool J and anything else that wasn’t “mainstream” at the time?  Heh.
