Well I’m designing a expansion board for my NGW100.
It will have Audio (CS4202), PS/2 ports with the required level shifters, VGA (ADV7125), a 128×64 monochrome LCD and some interesting power circuitry.
Whats interesting about the power circuitry is it will be able to take half a dozen different power sources to power the NGW100.
They include USB power, Solar, Wall wart and power from a lead acid battery.
It will be monitored by a ATmega32 (which also runs the LCD) and the NGW100 will be able to inquire about voltages and battery capacity. 
Attached is 3d renders of my monstrosity.
I’m trying to cram all this stuff in to a very small space. I’m limited to 10cm by 8cm.
Also the power circuitry isnt done yet. It will fill the blank space.
