The people have asked and we here at Mobius Strip Technologies have answered. The first RGB board made specifically for the Philips CD-i 400 and 500 series. This board is a completely custom circuit designed in house. It offers a proper 0.7Vpp RGB signal, 0.35Vpp 75ohm combined sync (CSYNC) signal, and a TTL CSYNC signal. Sync signals are built from the H-Sync and V-Sync signals directly from the video encoder to ensure proper timing. This sync signal is 100% compatible with the OSSC, as well as Sony PVM’s. DIY Installation documentation is available from our Tutorials section.

Frequently Asked Questions

Why choose this board over the “PC Engine amp-based”¬†modification found online?

  • Sync signal is not using Composite Video which can cause noise and failure to sync on some devices.
  • RGB levels are a proper 0.7Vpp versus >1.0Vpp signals seen on the “PC Engine amp-based” modification
  • RGB and 75ohm CSync signals are 100% safe for use with the OSSC and consumer grade devices. No risk of damage due to over-voltage.
  • Built-in RGB Enable pad. No more soldering in a pull-up resistor.
  • Accurate color reproduction matching OEM output.

I don’t have a 400/500 series, will this still work?

  • Compatible with all Philips CD-i consoles with a BT9106, BT9107, or BT9108 encoder.
  • A list of models known to contain this encoder is as follows:
    • 210/40
    • 210/60
    • 220/60
    • 220/80
    • 220/97
    • FW380i
    • 450 (Tested Working)
    • 470 (Tested Working)
    • 490
    • 550 (Tested Working)
    • 5000
    • 9000
    • GDI-700M
    • GDI-750
    • GDI-1000
    • TV: 21TCDI30
    • 740/00
    • 615/00
    • 660/00
    • 670/00
    • DVS VE-200 (Tested Working. Requires Resistor Swap.)

Does this work with HDRetrovision cables, RAD2X, Genesis/MegaDrive 2 SCART cables?

  • Yes. This board can be made to work with these cables.
  • Simply remove and bridge the 75ohm resistors and 220uf capacitors on RGB lines. And use the TTL CSync pad for sync.

Can I use this on a PAL CD-i?

  • Absolutely. This board is compatible with both PAL and NTSC CD-i units.
  • Please note this board does not modify refresh rates, enable switching refresh rates, or convert from 50hz to 60hz or vice versa.
