Hi, I will run some test games this week against different computers. I played several blitz-5min games today myself and by the feeling its strength is close to Excalibur Grandmaster which I had faced past week... But we have to keep in mind that 8086 at 5Mhz has a perfomance of 6502 at only 2Mhz, so unit's hardware is quite weak...

By the way: which time control could be suggested according to DEBYUT's design of levels for so-called Active chess?

Unit's dimensions: 26x23x3,5 cm
