Single-Board version of X65, now on Hackaday

February 20, 2024

In the last 2 months I have re-done my X65 double-decker computer into a Single Board Computer (SBC).

The single-board version fixes some of the electrical problems I had on the first version and it has way better signal integrity thanks to the 4-layer PCB. Other than that, the feature-set is basically identical.

added the mono speaker with volume control.
added (Olimex) UEXT connector - 2x5 pins connected to the NORA FPGA.
added internal bus extension connector 2x10 pins.
added DIP switches and internal status LEDs.

The complete Kicad project is on the github as usual: X65-SBC.

I have also created this as a project on Hackaday: X65-SBC.
