   @GabeMoralesVR The A3000 RTC circuitry has a 4-bit data bus and 16 addressable registers. The CPU can directly read/write any of them, but there are no interrupts and no DMA.

   The official PCB schematics are here:

   I've been using KiCad to view the gerbers, but the schematic diagrams seem to have some mistakes so I don't trust them.
