On the main Atom board is the 16K memory extension card situated with an rechargeable battery to keep the data on the CMOS chips when power is down. A small printed circuit board with some wires (8K CMOS) replaces the 'high' VDU memory. Another tiny card on the left switches the video by means of a relays from the 80 column card the to the standard Atom graphical modes. That's why the video cable goes to the Atom. |
