Motorola Application note AN-932, "Application of the MC1377 color encoder" The special delay lines and coil used to be listed as a seperate category in the TOKO section of the Digi-Key catalog. They may still carry them. Remember that the horizontal line period has to be 63.555 microseconds and the vertical period has to be 16.683 milliseconds for any NTSC equipment to come close to accepting the output. This rules out mono and hercules cards. Mark Zenier markz@ssc.uucp mzenier@polari.uucp
