+    Sharp FontWriter series
+
+    Skeleton driver by R. Belmont
+
+    Main CPU: ROMless Mitsubishi M37720
+    FDC: NEC 72068 (entire PC controller on a chip)
+    512k RAM
+    Custom gate array
+    640x400 dot-matrix LCD
+    
+    Things to check
+    - Hook up 37720 DMAC, it's used before this dies
+    - Check if "stack in bank FF" bit is used
+    - Verify timer implementation
