I recently purchased a new Mimeo PCB and have noticed that the solder mask seems to have a brushed effect which is actually much more noticeable in real life than in the photos I've attached.
The PCB substrate also looks much lighter than most other PCB's I've purchased in the past so not sure if this is closer to original Apple-1 as I've never actually seen one in real life only in photos. I've tried searching for other images of Mimeo boards and the substrate seems darker. Not sure if this is a recent change?
Also the the edge connector contacts look like they are sanded, not sure if this is normal as well?
I would like to make sure this is all normal before I start soldering components on.
I am slightly color blind so guess that doesn't help!
