I need help with an Apple IIe Pal Colour Card

I am unable to find any documentation or even discussion about this PAL colour card. At first I thought it was simply an Apple II series PAL encoder card but that's not the case.  

 

The card itself has markings "Apple IIe Pal Colour Card" and "A2A005". Looking at the connector it appears to fit a regular slot and I wonder if this card can be used in slot 3.  I also need to know about the connectors - one is a four 4 pin connector to a header and the other one is a thin black one which connects somewhere else.

 

I should point out that I use a Platinum //e (NTSC International IIe which outputs 50Hz) and only displays monochrome on a composite input to an LCD TV. It does of course produce colour with my Apple Colour Composite monitor. If this card can produce PAL colour for my NTSC IIe then I should be able to get colour output to my TV.  Unless of course I'm barking up the wrong tree.

 

 

Any help appreciated.

Can you please provide a picture of the back as well? (Preferably the same resolution as the second picture.)

Also what are the markings on the Q1 and Q2 transistors?

 

One thing I can tell you from looking at the front side is that it uses the SYNC pin (pin 19), so it must be in slot 7 (the very last slot) in order to work. The blue cable probably plugs into the 4-pin connector in the upper right corner of the motherboard labeled MODULATOR, but I am not certain without seeing the back of the card.

J13

The 4 pin connector is plugged into J13 near the composite video output. It's single wire goes to pin 2 of this header, picking off the composite video after it is amplified but prior to the 75Ω source termination. The clip wire goes onto the leg of some IC, probably something that it can use to change the video timing.

Or maybe it is used to force monochrome mode, similar to what SW1 does on the PAL version of the Apple IIe.

Most important part of this is "MUST BE IN SLOT 7" due to the signal that is only there.  For a ][+ you really want an 80 column card in slot 3.  This card only provides color (colour), not 80 columns.

You are correct about the 4 pin connector.  The clip connector, that's the one I don't know where it goes, and I don't think the card will work properly without it connected correctly.

I see. The brown cable with the clip is directly connected to slot pin 23 through a bowtie on the back side of the card. The reason for this can be found in 7-18 of "Understanding the Apple IIe". If your motherboard is Rev.B, you need to just join the X7 pad with some solder and not connect the clip to anything:

 

 

If however you have Rev.A there is no X7 pad on the motherboard, so you need to connect the clip to GR+2, which is pin 21 of the Video ROM:

Wow, the official PAL Card

Wow, the official PAL Card for the Platinum Apple IIe International NTSC which sold for A$135 in Australia (attached pricing).  Never laid eyes on one before, thanks!
