In Feb 1979 I wrote a letter to Fidelity Electronics asking for information on Chess Challenger 10. Here is a synoposis of what they wrote back with: The processor was a Z80A (probability running a 4 Mhz.) The software could analyze 35 chess positions per second. The following table shows how many moves it searched at each level where X = all moves level depth (plys) TIME 1 2 3 4 5 6 1 X 5 Seconds 2 20 X 15 Seconds 3 16 24 X 35 Seconds 4 20 8 4 1.5 Minutes 5 20 8 4 2 2.5 Minutes 6 X X X X 1 Hour 7 X X X X 24 X 24 Hours 8 20 24 4 4 X 11 Minutes 9 20 12 4 4 X 6 Minutes 10 16 24 4 X 3 Minutes For those of you that never owned any of the Chess Computers back in the 70's may find these postings pointless but for those that did, info on old chess computers brings back memories. Though I suppose in 20 years someone will be telling how strong CM6k, Fritz5.32, Craftyxx.x, Rebel10, .... was and the hardware they were run on.
