Re: SB 2.0 CT1350 CMS chips dumped

In seeing how to get rev4 and up models working Ive socketed the chip and will swap them out to see what happens. As I figured the pinout continues to be the same across both board revisions. Filename 20180128_182002.jpg File size 641.51 KiB Views 601 views Filename 20180128_191551.jpg File size …

Re: SB 2.0 CT1350 CMS chips dumped

Wow sharp eye goodtofufriday. Do the CMS chips work on 1336A with your modification?

Ive ended up with a rev 3 and rev 5 versions of the 1305b card.

Matx, socket 462, agp, pci, isa The previous owner's work is embarrassing. Nice job cleaning it up. Agreed, a few of the bodges were bridged too. I'm …

Re: Repaired a Voodoo 5500 AGP - Now what?

Build a rig around it :) Coppermine 1000 or Tualatin/Tualeron should do nicely and is the most picked way to go around here. Don't plug it into a P4 without checking if the board works with AGP 2x cards though (unless you like having to do some more repairs that is :P). Any AMD options these go …

Repaired a Voodoo 5500 AGP - Now what?

I never really expected to own one of these cards, so I know next to nothing about what I can really do with it. Any place to start? Here are a few fictures of the repair.
