SMASH TV (Williams, 1990)

This is a two-board set in the Williams Y-Unit series.

The CPU board is identical to other Y-Unit games, but
with its own set of PLDs and ROMs.

The sound board is similar to the one used in StrikeForce,
and can probably be found in other Y-Unit games.  The ROMs
are the only programmable parts on this board.

CPU board: 5770-12555-00, Rev.- [yes, a dash]
- All CPU board ROMs are marked "LA1"
- ROMs are paired low/high (e.g. u89/u105 = low/high halves of 16-bit words)
- A sticker is marked "A-13234-3044 (16-8850-289)".
- The PLDs are "A-5346-3044-n", with n = 1,2,3,6,7,8.
  There is also a PLD marked "A-5345-4001-5".
  They are dumped below.  The two PALs appear to be secured.
- Seven ROM slots (U90,U91,U92,U93,U98,U109,U114) are left blank.  
  All RAMs are filled.  Game ROMs are 27010 at 150 ns, and game 
  RAMs are TMS4461s at 150ns.
