HYDRA “Quick Start” Demos

The HYDRA is more or less a minimal part count gaming platform to show off the capabilities of the Propeller chip. The hardware around the Propeller chip enhances functionality and interfacing, but doesn’t add computational elements, thus all work performed by the HYDRA is solely the responsibility of the Propeller chip.

Your HYDRA is pre-loaded with a simple “Asteroids” clone demo programmed into the on-board serial EEPROM at U4 (top left of the Propeller chip).

We will use this to test your system out. The following are a series of steps to try the demo out and make sure your hardware is working and a stray high energy neutron didn’t damage your EEPROM!
 
Step 1: Place your HYDRA on a flat surface, no carpet! Static electricity!
Step 2: Make sure the power switch at the front is in the OFF position, this is to the RIGHT.
Step 3: Plug your wall adapter in and plug the 2.1 mm power connector into the female port located at the top-left corner of the HYDRA.
Step 4: Make sure the XTAL marked 10 MHz is inserted into the XTAL port, top-center above the Propeller chip at J13. It’s possible that during transport the XTAL came loose and
isn’t inserted all the way and/or is loose in the packaging, so make sure the XTAL is inserted.
Step 5: If you have plugged the cartridge into the system, then UNPLUG it – we want to run the code off the serial 128K EEPROM memory which is on-board (located top-left above
the Propeller chip).
Step 6: Insert the A/V cable into the yellow (video) and white (audio) port of the HYDRA located top-right of the board, insert them into your NTSC/Multi-System TV’s A/V port, and
then switch your TV set to “Video Input” mode.
