Clone of the Fidelity Chess Challenger 7

Infos

An analysis of the XD-300 revealed what it seems to be a clone of the Fidelity Chess Challenger 7. There are some minor differences, for example, the pads between the keypad and the sensors underneath the board are very different giving a different feeling when you press the keys. Not better or worse, just different. Also, it uses a true speaker instead of a piezo beeper as in the Fidelity Chess Challenger 7. But the hardware architecture is the same (CPU type and signal clock, RAM, etc.), and the content of the ROM is identical.

This seems like a modern (and patched) version of the same computer (1982?)
