my friend found 2x Pentium Pro with 512kb of cache, from an old server, so he gave 1 to me along with the heatsink.

Now i would need to find a board for it (Socket 8), for a regular ATX case. That would be awesome to, possibly, replace my Pentium 1 board (Socket 7).

Does anyone have that kind of board, unused, somewhere?

Here's a link to the CPU specs:
