+
+    Milton Bradley Phantom chess computer
+
+    TODO:
+    - no romdump of MB version yet
+    - sort out fphantom memory map
+
+-------------------------------------------------------------------------------
+
+Milton Bradley Phantom (1983):
+sold as Milton in Europe, Phantom in UK, Grand Master in USA
+
+Hardware notes:
+- CPU: SY6502A, 2MHz?(resonator)
+- ROM: 2x8KB?, labels C19679, C19680
+- RAM: 2KB 4*2114
+- magnetized x/y motor under chessboard, chesspieces have magnet underneath
+- piezo speaker, LEDs
+
+
+-------------------------------------------------------------------------------
+
+Fidelity Phantom (1988, model 6100):
+
+Fidelity bought the design from Milton Bradley and released their own version.
+It has a small LCD panel added, the rest looks nearly the same from the outside.
+
+Hardware notes:
+- CPU: 6502, 5MHz?
+- ROM 2*32KB
+- RAM: 8KB?
+- LCD driver, display panel for digits
+- assume rest is same as MB version
+
+After Fidelity was taken over by H&G, it was rereleased in 1990 as the Mephisto
+Phantom. This is assumed to be identical.
