>I got a new MCU D8751H for the Quizard 3.

Congrats.

The Quizard notes section could be updated in the meantime...but

-
src/mame/drivers/cdi.cpp


/* Quizard notes

The MCU controls the protection sequence, which in turn controls the game display language.
Each Quizard game (1,2,3,4) requires it's own MCU, you can upgrade between revisions by changing
just the CD, but not between games as a new MCU is required.

The only dumped MCUs are German region ones for Quizard 1 and 4.
A Czech Quizard 4 MCU was located but it was an 89c51 type instead

yep....at lot more work ahead for src/mame/drivers/cdi.cpp file.

TODO:

- Proper abstraction of the 68070's internal devices (UART,DMA,Timers etc.)
- Mono-I: Full emulation of the CDIC, SLAVE and/or MCD212 customs
- Mono-II: SERVO and SLAVE I/O device hookup
- Mono-II: DSP56k hookup
- Mono-II: Move 68HC05 I/O device hookup into CPU core



>I really hope we get a D8751H for the Quizard 2 soon too.

Good luck with continued search.
