First (?) version of the AES board, made (and maybe assembled) by NEC. Uses the first generation chipset (PRO-B0, PRO-C0, LSPC-A0) and exclusively works with 5V power supplies.
In late use of this board version, a video PLL and the NEO-POWER-0 power supply daughterboards were added on top.
Some consoles also have an added metal shield connected to ground.
