Re: [MZ-80 K] Serial interface through I/O ports $F8-$FF
RESET: you're lucky! 
I didn't check it and wasn't sure because in numerous schematics or tables about SHARP MZ you can read some signals named without negative marks while they are active negatively. So always double check as you did

Re: [MZ-80 K] Serial interface through I/O ports $F8-$FF
Revised my last post as I made a big mistake in the way to handle /CSEx. In the end, using /CSE should be enough.

Re: [MZ-80 K] Serial interface through I/O ports $F8-$FF
Beware! $F000-$FFFF are used for ROM like floppy disk drives. On MZ-80 K, $Ex00-$Ex27 is the I/O memory mapping, so you can get an unused /CSEy signal where its address range is [$Ex00 + y*4, $Ex03 + y*4]. 'x' means whatever the hexadecimal digit in place, you'll get a mirror of $E000-$E027. Since y...

Re: [MZ-80 K] Serial interface through I/O ports $F8-$FF
If your DIY project only concerns the MZ-80K, everything below 0xF8 should be safe.
EDIT: I believe MZ-80AIF is for MZ-80 A and MZ-80FIO for MZ-80 K.

Re: [MZ-80 K] Serial interface through I/O ports $F8-$FF
I move this post into its own topic because the one where it was posted was about I/O memory port through /MREQ.
And I think this post can legitimately have its own topic.

Re: [MZ-SD2CMT] GitHub link
No idea. Arduino IDE is doing something with the .ino file so the order of functions is not an issue unlike in a true C++ file. So I wouldn't expect such an error. By the way, I'm using Visual Studio and an Arduino plugin so I can benefit all the goodies like refactoring and smart c++ checking. I'll...

Re: [MZ-800] Different Video output box
Now the unknown signal through my second MZ-821 (without composite signal): signal-10µs-8MHz.jpg signal-5us-16MHz.jpg signal-1µs-48MHz.jpg Now wonder there is no color: no color-burst. There is also an interrupt "MONITOR <-> TV" but I got the same results. So I guess the only way to get co...
