  • Z80 (CP/M) Writing to SD Card
  • Log     from 3-Chip Z80 Design
  • Digging into SD card writes means shifting gears from the Boot BIOS source code since the Boot BIOS code only does reads. The CP/M BIOS code (CBIOS128.LST) which does the reads/writes after booting. Here's the BIOS code for writes to the SD Card: 0754...

  • Could this work?
  • Log     from EDIDone - Disable DisplayPort Hotplug
  • I recovered the project file from my drive and made some changes to it. The question is, which wire goes where? I won't know for sure until the dummy plug arrives, but the AUX line is definitely used for this purpose. I even created an EDID data for...
