The board fits on Arduino UNO board and its compatible with all arduino boards and IDEs . the only needed pins Are VCC , GND , RX , TX. The board has VGA (DB15) and AV Composite ports for TV and ...

[Damian Peckett] has implemented an Apple ][, its 6502 processor, and a cassette port, all on an Arduino Uno. If that wasn’t enough, he also uses a PS/2 keyboard for input and outputs analog VGA.

The Arduino is fast enough to support the ISA bus speed, but the card also needs the PC’s clock line to operate, and it only supports three modes: 80 x 25, 16 colour text, 320 x 200, 256 colour ...

The VGADuino-II, is a Graphic Shield specifically designed for Arduino with a higher resolution, and higher speed and offers support for 256 colours. Check out the video below for more details.
