# Monochrome Video
- [VGA](./vga.md)

- need 307&thinsp;200 bits => 38&thinsp;400/0x9600 Bytes 
- 8K character memory

- 1x 64K RAM
- split in half
- each half into page (0x0000 - 0x4AFF)
- map character memory into top (0x6000 - 0x7FFF)
- offset of 0x6000 into memory bus -> (0x6000 - 0xAAFF), (0xC000 - 0xDFFF)

## Design
- derive CS from bank register, leave LSB free -> wire to MSB of VRAM address
