Then wouldn't it suggest that Chess Tiger 15.0 for PalmOS running on the
Tungsten-C is (at least) in the same ballpark as Cray Blitz before multiple CPUs
and Belle 1983?
Also it suggests that the (future) native ARM version of CT15 running on Palm
Tunsgten-C would be in the same ballpark as Hitech 1985.
Naturally it's a little bit hard to tell because we know that elos can drift
over time. If think it suggests that these computers are probably not very far
in playing strength, at least they are in the same class.
