I had to resort to Internet Explorer, and even there the navigation was somewhat broken, but the archive in Szentes appears to have scanned and webbed a bunch of 18th century tax lists that they have in their possession. The lists are in Latin, naturally. The one I opened (more or less randomly, because I couldn't figure out what it was doing) was for Vásárhely. (It didn't say which one, but given the location of the archive, I presume it was Hódmezővásárhely.)
