someone mentioned a while back that the Laser line of apple // clones
has a modified video circuit which uses interlacing to eliminate the
distinct border between horizontal scan lines.  Apparently this is most
effective with a fairly high persistence monitor.  Well, is anyone out
there knowledgeable enough to give me a hand in doing this for my //c?

There is a video connector on the back panel of the //c which has
(i hope) all of the signals necessary for creating RGB or composite
signals.  I guess what i need to do is to somehow offset the second
refresh to fill in the gaps between scanlines...  If anyone feels
capable enough and willing to engage in a little email correspondece on
the topic, please write to me.  Then i can fill you in on the technical
stuff which you might need.   

Thanks very much.
