I think a tournament on slow hardware (386-16 to 386-40, or 486 <=33MHz)
including top programs of the early 90s and programs of today would be very
interesting. We could amongst other things see if there have been really no
advances in software in the last 10 years.
It looks like we have a lot of people out there ready to organize "at home"
computer tournaments. It shouldn't be very hard to find 2 (or even one) 386, or
even one slow 486, and let programs play on this hardware.
My bet is that the results would be much more interesting -and maybe more
surprising- that the Xth tournament between Fritz5.32, Hiarcs7.32, whatever7.32,
and so on.
Volunteers are welcome! I'll be glad to provide you with the latest Tiger for
this event!
