okay i ordered one of those chips from a website and when i got it the rom socket was like a couple pins shorter than my stock one, and the prongs were like twicw as wide too. has anyone chipped thier shit? i have a P28, and the chip says it fits P08,P28,P30,P61,P91.

can this be right, if anyone knows about any of this chip crap let me know. i know how to build circuit boards and stuff and im pretty competent but this just doesnt look right.
