Hello all,
   I'm looking for the sync program that will allow a 720x484
(or thereabouts) on a Symbolics 3650 with Hires Chroma
paddle. I connected with Doug Evans a few months back
and he said there was one available (and that it was in the
public domain now). I'm not sure what it's called, but it's
something like CCIR-601 or D1...  and takes the form of
CCIR-601.bin.? or some such.  I recall seeing it on an
xl1200 I used for a while (although that was on a broadcast
res board) but that would be an ".ibin" file which probably
wouldn't work.
   Is there perhaps a repository of such things somewhere
on the net?    Thanks for any help you can provide!

Scott
