Thank you very much for the release matze.
I wish you some less stressful moments and hope you are getting better!
I will really make one of your cards 😀
Two small questions here:
- I seem to be unable to find the code/hex for the tiny. Is there a different repository for it?
- are the 2 issues (wrong oscillator, needed patch wire) fixed on the released files?
Thank you already!

Hi,

its rev from page #1, so its fully working.

The hex/bas file is here, it is pretty simple
the mcu also introduces a delay, without the delay the bios scan during boot (AT running Card on 0C0h) will unlock the gate and it will playback random sound until you send mute commands from booted os.
That is why i used a mcu instead of a punch of flipflop gates.
