# Open 'Tendo
An Open-Source HardWare (OSHW) recreation of the original 1985 Front-Loading NES motherboard.
## Note on RGB and HDMI:
Neither RGB nor HDMI video output were or are a goal of the OpenTendo project, the goal was/is documentation and preservation, and the project was an exercise in reverse engineering. As such "improved" video outputs will not be added to OpenTendo.
NESRGB and Hi-Def NES can be installed as normal, but will not be incorporated into the OpenTendo PCB

These are the only two parts that are custom and have no available replacement, the rest can be replaced with modern, and or easily available parts.
