Truco Clemente (c) 1991 Miky SRL

driver by Ernesto Corvi

Notes:
- Audio is almost there.
- After one game you can't play anymore.
- I think this runs on a heavily modified PacMan type of board.

----------------------------------
Additional Notes (Roberto Fresca):
----------------------------------
Mainboard: Pacman bootleg jamma board.
Daughterboard: Custom made, plugged in the 2 roms and Z80 mainboard sockets.

  - 01 x Z80
  - 03 x 27c010
  - 02 x am27s19
  - 03 x GAL 16v8b      (All of them have the same contents... Maybe read protected.)
  - 01 x PAL CE 20v8h   (The fuse map is suspect too)
  - 01 x lm324n

  To not overload the driver, I put the rest of technical info in
  http://www.mameworld.net/robbie/trucocl.htm

- Added 2 "hidden" color proms (am27s19)
- One GAL is connected to the color proms inputs.
- The name of the company is "Miky SRL" instead of "Caloi Miky SRL".
  Caloi (Carlos Loiseau), is the Clemente's creator.
