Neuer treiber: SciSys Chess Companion II und Explorer Chess. Danke an Sean Riddle fur ROM dump.
Even though the Explorer has less buttons, it's the same ROM as Companion II. Concord is also on this MCU, but other than aesthetics it is identical to Companion II.

This is the first chess computer with a Kaare Danielsen chess engine, and also the first Kaare Danielsen one that's ever emulated. It is the 4KB program.
Sean Riddle was finally able to dump the HD6301V1 MCU.
It's not known yet if or how HD6301Y0 (16KB ROM) can be dumped.
