 A Propeller-based peripheral support board for the RetroBrew Computers ECB processors.
-The is a peripheral support board for the RetroBrew Computers projects based on the [[https://en.wikipedia.org/wiki/Parallax_Propeller|Parallax Propeller P8X32A MCU]] as an intelligent I/O controller. The Propeller MCU is ideally suited to this role as it allows for simple connection of multiple peripheral devices and utilizes a custom EEPROM based firmware that can be enhanced over time.

-The V2 is intended to interface with a host processor/controller on the ECB bus such as the RetroBrew Computers SBC. The onboard EEPROM firmware of the board must be programmed with the correct firmware for the host processor/controller being used. The host software/firmware and the Propeller EEPROM firmware must act cooperatively using a prearranged protocol to communicate. At present, the pre-built V2 EEPROM firmware is intended to work with a host processor/controller running the RomWBW or UNA firmware.

-Note that the V2 does support a standalone operation mode in which it can be powered by a +5V DC Jack without being connected to an ECB bus. The idea is that it would be possible to create a Propeller firmware allowing the board to act independently of a host controller – perhaps acting as a simple single board computer or terminal emulator.

+The PropIO V2 supports the following peripherals:
 **VGA Monitor:** A DB-15 VGA monitor connector is provided and the board will drive any standard VGA monitor. The Propeller is capable of a variety of text and graphics modes. However, the current firmware implements standard 80×25 text. ANSI terminal emulation is built-in.

 **Speaker:** A small, low fidelity speaker is provided to allow generation of simple sounds. This is mostly intended to allow for various “beep” codes as desired. The current firmware does not allow the host processor/controller to directly control the speaker, but this should be possible with a simple upgrade to the onboard EEPROM firmware
