The Radio-Electronics NTSC-to-RGB converter in the October, 1990 issue might possibly be modified to convert PAL to RGB. The project uses two ICs (LM1881 and TDA3330) which according to their data sheets say that they both work with PAL (and SECAM). The obvious changes will be the crystal (4.43 MHz instead of 3.58 MHz) and a few chroma filters. A PAL 64 usec delay must be added which might be the biggest change. After looking at the data sheets and the R-E article, it looks possible. -- Dave Turner 415/823-2001 {att,bellcore,sun,ames,decwrl}!pacbell!dmturne
