Need this memory ram module identified 160 pin ROM maybe?

1-80 on one side 81-160 on the other side 4.5" long. It was a pull from a PB Legend I believe - don't quote me on that - definitely a vintage pull - I do remember it was NOT where the other memory chips were at on the motherboard

Info on the chip says IDT 7MPV6310-01

Just want to know what type of module it is

It's an L2 cache module for a power macintosh. Powermac series 7xxx and performa 6400/6500 used these.

YOU ARE A GENIUS! Thank you! Is there anywhere online that catalogs these??

Tough, this is getting quite old now, they were 1993-1996 vintage. These beige powermacs are totally obsolete.
Usually these are 256kB, but I suspect yours is 512kB.
