/***************************************************************************
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.
