6509 dissection: IDKFA

[org]

On behalf of the entire staff of the Breaking NES project, I express our gratitude to you!

Спасибо!

If you need anything in my schematics changed, just tell.

I know that re_writing a book of that size is a lot of work.

Жела́ю уда́чи! //good luck.

I'm going to wait with PPU bug reports until the book is finished.

A PPU dissection will take some time, because Frank has the priority.
Of course I will try to break my PPU schematics into smaller parts later, too.

BTW: for translation of words and phrases, I use Leo.

EU has startet pulling sanctions against the Russian federation because of the Ukraine invasion.
Part of the sanctions list will be: "no technology transfer, no shared research projects".

Until we know for sure how this maps to 'hobby projects aiming for 40 years old game consoles',
I have to put support for emu-russia on hold, just to be on the safe side.


org, sorry to bring this up, but it would be nice if your books won't say "ttlworks has helped",
because not all of the readers would be aware that I did the schematics before the Ukraine invasion.

Really, it was a pleasure to contribute to your project.... it also was "a culture shock":
Nice/friendly/competent people, trying to get something done with what's available, without "debating a topic to death".
I'm not used to that.

Good luck and god speed, looking forward that the political situation might be turning to the better someday.

I understand. Then we'll wait to see how it ends.

While waiting for Frank to finish that 6525 polygonisation, I had some spare time at my hands.

Has it occurred to anyone else that Frank and ttlworks operate like a 6502? Specifically, they overlap operations but they are never fully pipelined.

Three years later, while dissecting the 6571 core,
I noticed by accident that something went wrong with the polarity of the JB signal in my 6509 dissection.

I now fixed this.

Also, that error went into my schematic for breaknes,
and my fixed schematic for breaknes looks like this:

//This does not affect the schematics drawn by the breaknes team.
