was the v9958 not easy to interface in your schematics?
I will change specification to MSX2. But it will not change the meaning, value and user/learner experience.
maybe is better to use a v9958 and leave specs to msx2+. Great gfx...

yeah

It is not new msx. It is msx-compatible platform.
With GR8BUS you will use standard ISA breadboards for your developments. It has more signals that are important for system expansion than SL50. And finally, there're seven of them.
What problems are you talking about? I did not see any problems.
