RE: Scope Dual-Input Coupler ???

The last time I did this (I used a Tek 2445), I remember that I needed to
hook up an inverter to the Z signal to match the scope to the game. I used
a TTL chip for this purpose and it works great. If you don't do this, all
you will see are the retrace lines. That looks cool, too, but that wasn't
what I wanted. :-)

I'll bet that you are right -- and yes, the Z input is on the back of the
scope.

Ok, I just need a "Y-adapter" then -- anything I should look for in
particular? Know of a decent source?

Thanks
