PPC750GX vs. PPC750GL?
Posted by: Powerbase on 2025-09-20 08:59:34 I saw a picture of another version of the ZIF board: View attachment 91099 From here: stat.ameba.jp/user_images/20231223/17/ymf724v-f/6a/96/j/o0834062615380474042.jpg Ive never seen that style, clearly marked as a 750fx too with dip switches. Maybe a weird Japanese brand one.

Posted by: croissantking on 2026-04-05 14:38:46 I'm afraid I have missed the thread, but I have already made a replica of the PowerLogix 750GL accelerator... It however does not work as I did blow the VRM, so there's possibly a short somewhere in my design that I need to trace. I had a PowerLogix board that I recovered from a scrap lot, that was destroyed. It's an 8 layer PCB, and it was extremely challenging to both reverse engineer and assemble.
