+Pitfall II The Lost Caverns, Sega, 1984
+Hardware info by Guru
+
+This game runs on Sega System 1 hardware. The version documented here is
+the not-encrypted version.
+The same PCB runs a few other games, including some official Sega conversions.
+For example: My Hero, Teddy Boy Blues, Sega Ninja, Ninja Princess and several others.
+The bootleg Pitfall II PCB is an exact 1:1 copy, including using the same encrypted ROMs,
+and the custom chips have been replaced with plug-in daughterboards.
+
+
+Sega Game ID#: 834-5627-10 PITFALL II (sticker). Also seen: -11, -12 and -13 stickers.
+PCB#: 171-5054-02 (seen on some PCBs with (C) 1984). The (C) 1985 PCB does not have a 171 number on the PCB.

+Notes:
+ 315-5011 - Sega custom DIP40 IC \
+ 315-5012 - Sega custom DIP48 IC / The bootleg replaces these two chips with a plug-in daughterboard containing logic chips
+ Z80(1) - Z80 CPU. Clock input measures 3.76992MHz on first power on and changes to 3.65950MHz or 3.80062MHz during game play.
+ Replaced with encrypted Z80 with sticker '315-5093' on the encrypted version.
+ Some factory conversions have been seen with a plug-in daughterboard containing Z80, PAL and PROM and some later games
+ or later releases of the same game use a stock Z80 without encryption.
