Everything I've seen is like the basic 1861 design in the Elf-II article in
P-E:
http://www.infinet.com/~erd/retrocomputing/ElfII/ (10K resistor on
SYNC, 2K resistor on VIDEO, tied together and to ground by 1K resistor).
Perhaps I just need to play with the resistor values.

It's the standard COSMAC VIP. I'll scan the 1861 output section and post
a URL for it later tonight if I get the chance. IIRC, it looks just like
the Elf-II circuit. Nothing complicated.
