Well, "Third-Edition Rules with a First-Edition Feel" is the motto of Necromancer Games, IIRC, so that could be the place to start. Or, as Grail suggests, Mad Irishman, since that site has every sheet you could ever need.
EDIT: They do indeed use "3rd Edition Rules, 1st Edition Feel" as their motto, and they also have two "1st Edition Feel" character sheets (HERE and HERE) in their free downloads section. I think that's what you're probably talking about.
