When I was assembling all the PCBs for my MSX2+ project, I used all the compatible PCBs that were available in the MSX1. And since there were still the VDP 9918, the Beer IDE and the 64KB Ram from MSX1 project, why not build another one? 

To do this, it was necessary to assemble a new Clock, CPU, PPI, Clock and PSG.... PCBWAY minimum order is 5 pieces, so I still have some spare parts :)...
