Hi.  I just realized that the instructions for building the TTL RGBI to
analog RGB convertor I posted a while back left out one important point.
If using DB9 connectors from an ibm pc graphics adaptor, the connector
J1 ( the one that connects to the graphics card) must be mounted from 
the SOLDER side.  Also, if not using inverted sync - jumper pins
1 and 2, 3 and 4 of the 7404 - not the boxes as shown on the silkscreen.
Sorry for any problems this may have caused.
BTW - I still have plenty of etched boards if you are interested
