These pictures show that the Peri Beta is a "clone" of the Fidelity Designer 1500. In the first picture the Peri Beta is on the left and the Designer 1500 on the right. The PCBs are identical Fidelity components and the 80C50 processors are exactly the same. In games played simultaneously against both chess computers they replied with the same moves at the same time in most cases. There were very occasional differences in the middle game, when they responded with different moves at the same time. The chess program is weak, only being capable of finding Mate-in-2.
