Nintendo video inverter - which one?

[Guest]

Archived from groups: rec.games.video.arcade.collecting (More info?)

From reading around there appears to be a few possible Nintendo video
inverters - there's the Nintendo original, one made up of LM318's,
Mark Spaeth has apparently designed one, etc.

The thing is, which one is the best one to go for in order to
generically run any old Nintendo game?

I'm only too happy to make my own if someone can please point me at
the relevant schems, but if it's too complex then I'd rather buy a
suitable PCB and add the parts myself, or even buy a ready-made unit.

I see that Clay makes one but this appears to plug into an edge
connector, something which Space Fever boardset doesn't have (just the
usual multiple connectors).


Thanks

Did you see Mike's inverter + Amp board only ?

The ones I made a long, long, long time ago were just a copy of the
original inverter board with no improvements. The fab overplated the
holes, so the resistors wouldn't fit through, so I ended up trashing
all of the boards

To do it right, you really need a wide-band opamp that's spec'ed for
video applications. LM318's too slow.
