Re: REBEL 10 benchmark on modern computer

Hi Ed,
I just compare the speed for Rebel 12 under DosBox and under Qemu and both are running around 120 Kn/sec.

Re: REBEL 10 benchmark on modern computer

Yes, good idea.
I ran until Depth=11

13'983'914 nodes in 143 seconds = 97'789 n/sec

i7@4 GHz under DosBox full speed.

I'm working on VirtualBox but I'm not very successful yet.
