[comp.sys.amiga.hardware] Modifying A1300 Genlock

vincelee@tornado.Berkeley.EDU (Vincent H. Lee) (10/11/90)

Help.  I bought a 1300 genlock and am thinking of adapting it to my
500 (It works on my 1000 just fine).  I heard there might be problems,
but I can't understand why (the video ports are the same, aren't they)

Also, the 1300 seems to have problems syncing when certain games are
running, even if I have the thing switched to "computer only".  The 
problem seems to occur when the game is overscanned.  Can I fix this?
I was thinking of simply taking the composite sync signal generated by
the amiga and feeding this to the rgb out instead of whatever it 
generates.  Would this work?  Since the video is supposed to be synchronized
anyway, I can't see a problem.  This, of course, only takes care of the 
RGB out (which is what I care about when I only want to see the computer 
anyway)  
\
For the composite out, how about taking the computer's sync and feeding it
to the 1377 instead of whatever it uses?  Would this work?

I don't understand why I should have to unplug my genlock every time I want t
to run certain programs.  If anybody can help me, I'll be eternally in your
debt.

thanks in advance.
