I bought the only one I ever saw from Software Hut several years ago. Its still working and sealed away currently. Its got an 040 card from an A4000 in it, no Amber chip or the ability to have one, AGA and no working DSP chip, but the rest is there and its in a standard A3000 case.
So
you bought it! Well, mystery solved. Glad it went to a good home!
(Hope you checked the battery!)
