Hi,
no the Sapphire does not run with the Citrine chessboard ...
As far as I know, only the first version of the Sapphire I was running with 20 MHz clockspeed ... I think, the only way is to open the computer or compare the solving time in the BT test with other units ... but then you have to know how fast the other one is ...
Maybe there is a way for reading out the information with the computer interface ... but ... I think it is no problem to open the device ... and it is the fastest way ...
Kind Regards,
Sascha
