+SciSys Mini Chess, pocket calculator style chesscomputer
+It's the first chess program on HMCS40, the engine was written by Mark Taylor.

+Hardware notes:
+- Hitachi 44801A34 MCU @ ~400kHz
+- 4-digit LCD screen
+
+Excluding resellers with same title, this MCU was used in:
+- SciSys Mini Chess - 1st use
+- SciSys Junior Chess
+- SciSys Graduate Chess
+- SciSys Chess Partner 3000
+- SciSys Chess Partner 4000
+
+On CP3000/4000 they added a level slider. This will oscillate the level switch
+input pin, so the highest level setting is the same as level 2 on Mini Chess.
+It works on the old A34 MCU because the game keeps reading D0 while computing.
