Hi,
yep, everything is correct. Maybe the Mephi III is higher in the list because it was always taken a 6.1 MHz Version and games with Mephi II were played more often with 3.5 MHz ... also, the Mephi II ESB is stronger than the normal Mephi II.
So I am not sure which computer would win a match of 20 games, the Mephi II ESB 6.1 MHz or the Mephi III with 6.1 MHz.
Regards,
Sascha
