45Notes:
46      Connectors
47      ----------
48      CA - Cartridge connector
49      CB - Power Input connector
50      CC - Composite Video and Audio Out connector
51      CD - Printer Cassette Motor connector
52      CE - Printer Data connector
53      CF - Printer Head connector
54      CG - Paper Sensor connector
55      CH - Joystick connector
56      Connectors on the back of the main unit include RCA audio (left/right), RCA composite video,
57      24V DC power input and contrast knob.
58      On top of the main unit, there is a reset button, on/off slide switch, a big eject button, a
59      button to cut off stickers after they're printed, a button to open the hatch where the sticker
60      cassette is located and a red LED for power.

62      IC's
63      ----
64      BIOS2.LSI352- Hitachi HN62434 512k x8 (4MBit) maskROM (SOP40)
65      CDT-109     - NEC CDT109 (QFP120). This is some kind of CPU, the package looks a bit
66                    like a V60. The BIOS is tied directly to it.
67      RH-7500     - Casio RH-7500 5C315 (QFP208). This is the graphics generator chip.
68      RH-7501     - Casio RH-7501 5C350 (QFP64). This is probably the sound chip.
69      SH7021      - Hitachi HD6437021TE20 SuperH RISC Engine SH-2A CPU with 32k internal maskROM (TQFP100)
70                    The internal ROM (BIOS1) is not dumped. A SH-2A software programming manual is available here...
