The Fidelity  Chess Challenger needs no introduction
Released in 1977, it was the very first dedicated chess computer available to
the buying public
Invented and Programmed by Ron Nelson, it ran on a 8080 AF processor running at
2Mhz with 2k of ROM
it had one level of play
A total of 1000 were made and  it sold for about $350-$400

since neither Nelson or Samole(President of Fidelity) were serious  chess
players they made the now infamous mistake of reversing the ranks and
files,causing the move input system to be totally reversed

to play the normal D2-D4 the owner had to key in..4B to 4D



Fidelity quickly corrected the gaff with the Chess Challenger 3
owners of the CC1 could send in their computers to the Fidelity Factory for an
upgrade to the CC3
in addition to correcting the notation they increased the number of levels to
three

in this photo the reversal of rank and file can be seen as well as the reversed
notation in the display screen:
