Hi.  I recently bought a p.c.board set for the arcade game Defender and I'm 
trying to get it hooked up but I don't know much about color tv workings.
I'd like to hook it up to a color tv (thru the composite video input
on my VCR).  For the video it has the following outputs:

  R, G, and B:  analog, vary from about 0-3vdc
  Sync signals:  TTL levels
    Vert. Sync: a 60hz signal (positive pulse about every 17ms, 0.8ms wide)
    Horiz Sync: a positive pulse about every 18usec, about 2usec wide
    Composite sync:  combo of H and V
      
Is there some standard for video game monitors?  Can I run this thru
an MC1377 RGB to NTSC converter, or will things not work because it
doesn't have the proper scan rate as normal TV?  If so, how close do
you need to be for a normal TV to sync up?  Otherwise, what else
could I use as a monitor? (I could go to an arcade parts place and
pick up a proper RGB monitor for about $200).  Can I use one of those
IBM/PC multisync monitors instead (then I could use it for more than
just the video game)?

Any help appreciated...Mark
