What would an Apple Powermac motherboard be graded at. It comes in two pieces but there isn't a removable CPU. Thanks in advance

Smll socket for embedded versions (soldered cpu) and large socket for many but not all Power (vic) macs with the large rectangle pga. You'd need to post a picture to be sure.

Thanks. Here are pics of the front and back of each board. The smaller one was attached to the front of the bigger one. Thanks a lot for the help.

One on the left is small socket or large socket. You'll need to measure the length.
One on the right is the cpu card. Green fibre with metal class.

So measure the length of socket on the bigger one and the smaller one would be green fiber CPU with metal? Just want to make sure. I really appreciate the help.

Yes. The large socket motherboard rate is based on greater than 7 inch periphery. so measure the sides and add them. That port, the tt-pga socket, comes in a few sizes most commonly 1.5x0.5 (4in) and 1.75x1 (5.5) and 2x1 (7)

Yes. Mac cpu cards go as green fibre with metal rate.

Thank you so much for your help. I got 7 of these units for $2 a piece and was trying to figure out my profit on them.
