Connecting to a display

Unless you want to use the ICE Felix display or a TV tuner, you can use the RGB video connector from the HC 2000 to convert the signal to VGA (CGA to VGA converter). One that is cheap and easy to use is Gonbes GBS-8220 CGA/EGA/YUV to VGA converter (manual). Besides the converter, you will need a cable with a D-SUB 9 pin male connector at one side, that gets plugged into the HC 2000. The connections should be as following:

  • Red Video to Red Wire ( R )
  • Green Video to Green Wire ( G )
  • Blue Video to Blue Wire ( B )
  • Horizontal Sync to Gray Wire ( S )
  • Vertical Sync to Yellow Wire ( VS )
  • Ground to Black Wire

Another option is to take Composite Out (pin 7 from the D-SUB DE-9 video connector) and ground (pin 2) and route them to SCART or RCA connectors. If you’re going for a D-SUB DE-9 to RCA cable, pin 2 (DE-9) should go to RCA barrel and pin 7 (DE-9) to RCA central pin. A D-SUB DE-9 to SCART cable should connect pin 2 (DE-9) to pin 17 (SCART) and pin 7 (DE-9) to pin 19 (SCART).
