+Direct writing of the VERA's memory can be performed via [VPOKE](https://github.com/X16Community/x16-docs/blob/master/X16%20Reference%20-%2004%20-%20BASIC.md#vpoke).
+
+Details about programming for the VERA video adapter can be found in [Chapter 9: VERA Programmer's Reference](X16%20Reference%20-%2009%20-%20VERA%20Programmer's%20Reference.md). In particular, please refer to the sections on [VRAM Address Space Layout](X16%20Reference%20-%2009%20-%20VERA%20Programmer's%20Reference.md#vram-address-space-layout) and [Tile mode 1 bpp (16 color text mode)](X16%20Reference%20-%2009%20-%20VERA%20Programmer's%20Reference.md#tile-mode-1-bpp-16-color-text-mode). All text modes use Tile mode 1 bpp (16 color text mode), with 128 tiles per line and 64 lines, even though the display will not show the entire range at once.
+
+The video memory for all text modes start at VERA bank 1, address $B000. (e.g. `VPOKE 1, $B000, 0`).
+For mode $80, bitmap memory starts at VERA bank 0, address $0000. (e.g. `VPOKE 0, $0000, 0`).
