no.. there is a card that is am/fm but it is not a tv tuner.. and it is an ISA card. it's called the cadet.. if you search the fourm you will be sure to find more info on it, but no.. I've contacted many companies directly and it seems that no one makes an AM tuning card. The problem is the inherent noise of the computer.. it makes AM tuning difficult.
If you find any info let us know!!
