    NUBUSPAS16-DB :: A daughterboard hack to restore some functionality of a standalone MediaVision PAS16

    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 !

    NUBUSPAS16-DB :: A daughterboard hack to restore some functionality of a standalone MediaVision PAS16

    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...

    How do you use the image file ? I've been trying with DiskCopy but it doesn't like it (because no ressource fork I guess)

    Build log First remove bracket. Then desolder C101, C110 and the HD26 connector In my case C101 was dead, the card needed a recap anyway Assembling the daughter board This requires soldering all three jacks, both Molex connectors and both capacitors. Everything CMS can be assembled by your...

    NUBUSPAS16-DB :: A daughterboard hack to restore some functionality of a standalone MediaVision PAS16

    Introduction pitch A member of the forum gave me this card (without the matching breakout box) for R&D purposes. Sometimes R&D gives birth to something so here we are. The initial design for a breakout box was plagued with a few issues, like missing information about some custom chips and lack...

    Documentation about the 160/180 SPI Bus ?

    @Phipli No worries I 100% agree with what you said. @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...

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...
