Thanks ! I didn't have a blank bracket around but that's a good idea !
The "someone" is me. Don't bother, I found the resistors values. I did this project using your previous pictures, so thanks a lot !
Some measurements and subjective remarks. This has been benchmarked against a Quadra 650 board (Wombat). I did it to double check something wasn't broken with the daughter board
Output levels
The last notch on the PAS16 Control Panel volume is an overdrive, 100% volume is last position minus...
Thanks a lot ! I would keep the box, the card is more valuable this way, but you do you :)
The gerbers files and design has been released on GitHub here
Will try to release the measurements this week-end as well

Assembling the daughter board
This requires soldering all three jacks, both Molex connectors and both capacitors. Everything CMS can be assembled by your...
Introduction pitch

@croissantking just R&D, sorting stuff from the TODO list :). I kinda want to use another MCU in SPI slave mode and communicate with it from within MacOS. Hardware side is doable, software side we do not have any idea where to start...
Thank you for this. I read a few of the files but no motion of SPI.
the first file is similar to what you can read in "designing cards and drivers for the macintosh family third edition"
I'm assuming the Express Modem is the one using it. On the Express modem dev kit, everything point to using...
