@ -9,19 +9,26 @@ Hardware notes:
|
||||
- Hitachi HD63A03YP MCU @ 16MHz (4MHz internal)
|
||||
- 32KB ROM(TC57256AD-12), 8KB RAM(CXK58648P-10L)
|
||||
- LCD with 4 digits and custom segments, no LCD chip
|
||||
- RS232 port for Novag Super System (like the one in sexpertc)
|
||||
- buzzer, 16 LEDs, 8*8 chessboard buttons
|
||||
|
||||
TODO:
|
||||
- everything
|
||||
- if it turns out that the hardware is similar enough to supremo, merge drivers?
|
||||
- NMI on power-off switch, it sets 0x14 bit 7 for standby power (see below)
|
||||
- add nvram, MCU is missing standby power emulation
|
||||
- add lcd screen
|
||||
- internal artwork
|
||||
- rs232 port isn't working?
|
||||
- unmapped reads from 0x33/0x34
