Re: [MZ-SD2CMT] GitHub link

I finally fix the bug which prevents from a WAV file with a big size to be loaded safely. Now I can load a 45KByte game (F-RollSide) and run it with no issue. Man, 12 minutes to load it though.

Re: Unicard - is it possible to get it?

Ok, I was looking for a mk3c PCB but couldn't find it. I'm not an electronics expert but I certainly try to get electronics stuff. I guess with the right BOM and how to make the simple adapter, I could build one. So $54 for 10 PCBs? I guess I can build at least 3 for my MZ-700, my MZ-800, and my fut...

Re: Unicard - is it possible to get it?

Interesting! I wasn't sure about the version of DirtyPCB. The thing is it seems to be for the MZ-800. I'm much more interested in the MZ-700 version and soon in the MZ-1500 version too and I cannot find whether they would be some differences. I would love to contribute to the development. I can also...

Re: CRT Chaser Field

Indeed...

Maybe the WAV needs some filterings to be handled properly.

Re: CRT Chaser Field

I guess BTX means "Basic TeXt". Did you try to load from the Basic?

Re: CRT Chaser Field

I believe there is MZF-Studio which can convert WAV<--->MZF in both directions. MZ-80B is supported.

Pretty cool little game for a BASIC game. The 2nd file is a data file. Quite fast scrolling in the game for BASIC (presumably it has a bit of machine code in there somewhere)
And there is no snow on the screen of the MZ-80 K - unless you only tested on an MZ-80 A?

Re: [MZ-80 K / MZ-80 A / MZ-700] undetermined $Exxx I/O range?

As seen above, while it may be possible to keep the I/O address range compatibility of an external I/O controller between an MZ-80 K and an MZ-80 A. It is harder to achieve it with the MZ-700.

Re: [MZ-80 K / MZ-80 A / MZ-700] undetermined $Exxx I/O range?

[ MZ-700 ] it also has a custom chip (IC 7A M60719) which outputs /CSE when in range $E000-$E7FF. Unlike MZ-80 A, I think this custom chip does not output an active /CSE when in the range $E800-EFFF because it would make impossible for an external I/O expansion to provide a ROM at this range. Howev...

Re: [MZ-80 K / MZ-80 A / MZ-700] undetermined $Exxx I/O range?

[ MZ-80 A ] it uses a custom chip: /CSE is active when in range $E000-EFFF. MZ-80 A-1.png But there is an extra circuit which combines /CSE and A11 to determine an access to I/O memory mapping ($E000-E7FF) or to SRAM/ROM ($E800-EFFF). MZ-80 A-2.png The circuit is a little complex here but it can su...
