How effective were those 2600 nodes though? Pioneer took several Hours (3:45:00)
on a Nadareishvili Study , most programs solve this with millions of nodes
instead of 200 like Pioneer!

How fast would Chess 4.x be on todays hardware? Can someone get a copy a test it
against Crafty or some other program?

I mentioned Ostrich but i was confused i am really looking for information about
Chaos. Chaos played some extreemly impressive moves for instance:

Chaos - Chess 4.0

[D] rq2k2r/3n1ppp/p2bpnb1/8/Np1N4/1B3PP1/PP2Q2P/R1BR2K1 w kq - 0 1

16.Nxe6!!  Chaos took 587 seconds to find this move it was searching 4500 nodes
every 3 minutes or about 25 a second.
Hiarcs 7.32 found this at 10/30 ply and 56.595.000 nodes 17:36
Gandalf found this at 7ply 5 seconds  450,000 nodes

Chaos was on a UNIVAC 1110 it looked at only 14,675 nodes this was on an
extreemly slow computer by todays standards and it would probably take a second.
