I have a problem with all my SBC I had, they have no standard BUS to communicate with external devices and no case. I ordered a old Siemens 505-6516 PLC chassis on Ebay to use as case, you can found these for cheap. I will need to swap the chassis backplane with a ECB-12 from RetroBrew since the original Siemens backplane is wire to be use as a PLC, so I also ordered the custom backplane ECB-12 from JLCPCB.

Now I need to wait for those to be delivered and I will began to work on that, I will post more update on this.
