Extended memory module for MSX

This is my first attempt to order something from a company PCBWay. I found it in Facebook. Surprisingly fast manufacturing and delivery, just two weeks from start to door. This is important - last one I waiting my order 8 weeks, from another seller. At first look, quality of PCB is pretty good. I ordered more than I need. But the quality is good, the superfluous ones were not needed. I think, next time I will try different color. But standart green look like professional part too.
