Pin Connections - Nakazoto/CenturionComputer GitHub Wiki
Pin Connections
We have beeped out 99.9% of the CPU6 board, except for some confirmations for bus connections or pins tied to VCC or GND.
The remaining pins are listed for confirmation, for future verification of schematics.
If you want to double check how the reverse engineering process is going, please check in with Sjsoftware, Meisaka or Chris Giorgi on the Discord.
