The Messy80 is just the second printed circuit board I have ever ordered. I got it from JLCPCB. When I received it the silkscreen was missing. As I ordered it I tried to follow their instruction as well as I could. What is interesting is that JLCPCBs online preview did show the silkscreen.

I have decided that before ordering the second revision of the Messy80 I will order a smaller board first, so I made a small adapter so that I can easily connect the Messy80 with ribbon cable to a breadboard. 

I have renamed the gerbers so that they follow the suggested naming patterns here:

Only the future will tell whether the silkscreen will show up this time.
