Boat Race improvements... [Roberto Fresca]
- Changed the game name to "The Boat". - Added year and manufacturer. - Improved the PPIs. - Fixed the VRAM size. - Added bookkeeping, coin, key in and key out for both players. - Added bets, start, big, small and others, but are still multiplexed. - Added coinage and test mode DIP switches. - Added specs and technical notes.

+*******************************************************************************
+
+ Hardware specs...
+
+ Seems based on MSX2.
+ PCB is marked "TVG01"
+
+ CPU:
+ 1x Sharp LH0080A (Z80-A). (IC26)
+
+ I/O:
+ 2x NEC D8255AC-2 PPI. (IC23, IC27)
+
+ Sound:
+ 1x GI AY-3-8910A. (IC18)
+ 1x Fujitsu MB3712 (audio amp) (IC2)
+
+ Video:
+ 1x Yamaha V9938 VDP (scratched) (IC13)
+
+ RAM:
+ 4x Fujitsu MB81464-15 (256 Kbit DRAM) (VRAM) (IC6, IC7, IC9, IC10)
+ 1x NEC D449C-2 (2K x 8 Static RAM) (WRK RAM) (IC1)
+
+ ROM:
+ 2x Mitsubishi M5L27128K for program. (IC3, IC5)
+ 3x Mitsubishi M5L27128K for graphics. (IC8, IC11, IC14)
+ 1x Empty socket for extra data. (*) (IC16)
+
+ Other:
+ 1x 21.47727 MHz Xtal.
+ 1x 8 DIP switches bank.
+ 1x 2x18 pins edge connector.
+ 1x 2x10 pins edge connector.
+
+
+ (*) Note: The CE line of the extra ROM that should be located in the
+ empty socket, is tied to PPI port B, D3.
+
+*******************************************************************************
+
+ Todo:
+
+ - Find the selector for the PPI2 port C multiplexed inputs.
+ - Demux the PPI2 port C inputs.
