This board is designed to be a FPGA expansion board using the standard Altera/Tersaic 40-pin header.
It adds a variety of legacy PC interfaces to an FPGA development board to aid in implementing and demonstrating retro PC hardware.
Adds the following interfaces:
- One HDMI Video Port
- One Serial Port (COM port)
- One Parallel Port (LPT port)
- Two PS/2 Ports (for Keyboard and Mouse)

**Experimental low cost versatile snake**
The initial requirement was for a 4 channel audio extention lead (PA snake) for use in domestic room with 4 active loudspeakers (left, center, right and sub) at the opposite end of the room to the control amplifier (and rear speakers).
Additional requirements to be added later were:
