Warning. Do not use the PCB I use in the video, it is not working correctly for some people so I suggest you do not use it.

I bought another faulty 8 bit micro from Ebay, this time it's an Toshibs HX-10 MSX and will be my first time seeing one in person as we all had speccy and c64 back in the day. It was sold described with no power, but it turns out the fault was no display- the dreaded black screen.
