+Notes:
+ Uses common 10-way/18-way Mahjong pinout
+ Z80 - clock 6.000MHz [12/2]
+ WF19054 - == AY3-8910. Clock = 1.500MHz [12/8]
+ UM3567 - == YM2413. Clock 3.579545MHz
+ HM86171 - Hualon Microelectronics HMC HM86171 VGA 256 colour RAMDAC (DIP28)
+ 6264 - UT6264PC-70LL 8k x8 SRAM (DIP28)
+ * - QFP120 IC marked 55102602-12. Logo on the chip is of two 5 1/4 inch floppy
+ discs standing upright and next to each other, with the corner facing up,
+ like 2 pyramids. The middle hole and head access slot are visible too.
+ Chip was manufactured 50th week of 1993
+ AR17961 - == Oki M6295 (QFP44). Clock = 1.500MHz [12/8]. pin 7 = high
+ VSync - 60Hz
+ HSync - 15.28kHz
