The A3400 is believed to be an early project name for what became the Commodore A4000. No A4000's were ever released with the A3400 designation, but they probably would have been supplied with the Commodore A3630 (with an 030 fitted). This board actually carries the names "A3200/A3400". The picture above shows the front bezel from the A3400. The LED board is marked "Commodore A2200 LED BD REV 1", Red = Ground, Green = HDD, Brown = FDD, Black = Power
