Notes:

paradise: I'm not sure it's working correctly:

- The high scores table can't be entered !?


penky: we need to delay the irqs at startup or it won't boot. Either one of
       ports 0x2003.r or 0x2005.w starts up the irq timer (confirmed via trojan)

Alternate dipswitch settings for Penky as found in scanned Pins & Dip manual:

Year is assumed to be 1994 based on 94*41 factory sticker and 19/1/95
operator sticker on a revised version PCB.  The year is not shown but
must be >= 1994, since the development system (cross compiler?) they
used left a "1994.8-1989" in the rom

Paradise (set 2): No board ID, although some tracks which are wire hacks on
 YS-1600 PCB are corrected on this version. All roms are labeled as "A-19"
 Except for the program rom all other data matches Paradise (set 1).
 NOTE: on this version of the PCB the above listed 4MHz OSC is replaced with
       a 3.579545MHz OSC

The Escape version might be the newest revision due to improved slot machine
 animation on 'girl select' compared to other sets. Except for the program
 rom all other data matches Paradise (set 1).

PCB Layout
----------

Looks identical to the YS-0402 but has no number printed on the PCB
  For vertical games, Yun Sung would take a known board reprogram the
  Actel A1020B but not give the PCB a specific number.  This was also
  done for Yun Sung's game Paparazzi.  See yunsun16.c driver
