I am currently enjoying the "oportunity" to use a composite color monitor
with my Amiga while my "MultiSynchronous" monitor is "AntiSychronous".
I decided to try to improve my outlook on life by disabling colorburst.
I took a working "setlace" program that sets the lace bit in gb_system_
bplcon0 and modified it to set/clear the COLORON bit instead. Sadly,
this did not work. Seems that it gets set to 1 whenever the copperlists
are built by RemakeDisplay().
While mucking with a copper-list disassembler (thanks, Matt) I ran into
a bizare setting. While it can't match any of Leo's gems, here is
a cute screen hack:

end

For the curious this TOTALY mangles the copper list, changing a MOVE
to bplcon0 from $A200 to $2000. It will only work if INTERLACE is OFF.
And, no, I won't tell you what it does.
