This is an old hardware question, so bear with me. Are there ANY TNT2
Ultra cards that are 1.5V?

Notches in the card are not reliable: a lot of TNT2 Ultra cards (maybe
most?) are improperly keyed, for both 3.3V and 1.5V slots, when in
fact they are only 3.3V.

And the designation AGP 4X is not reliable either. Even though the AGP
4X specs call for 1.5V, in fact, again, there are many TNT2 Ultra
cards that claim to be AGP 4X and implement at least part of the AGP
4X specs, but they are still 3.3V cards.

Indeed, and some TNT2 cards (like the heavily-marketed Diamond Viper V770)
reportedly support both 3.3V and 1.5V signaling, but require the user to set
a jumper on the card's PCB to select 1.5V. Even cards of the same brand may
see small design changes through its life due to cost-cutting, so 1.5V
capability may have gotten removed in a newer PCB revision. Just because I
say brand-X works at 1.5V, doesn't mean the card you buy will do the same.

So I just want to know which TNT2 Ultra cards, if any, are actually
1.5V.

The way you are asking the question, suggests you are looking to purchase a
TNT2 Ultra. Any reason a Geforce256 or Geforce2 GTS can't meet your needs?
These cards are certain to work at 1.5V. Prices should be about the same
nowadays.
