This item was shipped quickly and arrived very fast to the US. There is a nice quick start sheet if you haven't been following its progress on the Vectrex boards.
I ordered mine with a case and it is very well made and works great. I had my Raspberry Pi Zero with header ready to go with the SD image from Malban. You simply plug in the Raspberry PI with the SD card into the cartridge and insert it into the Vectrex.
I am now enjoying Arcade vector games and some need homebrews.
