I know AGP versions are out there, sometimes called Radeon 7200 or Radeon DDR. If a non-Mac PCI version exists, though, I've never seen it.

I am pleased to report that my modified card also works well in my 5400 running OS 8.6.

Wow, that battery failure was downright gentle compared to most I've seen.

What's stopping you from soldering pin headers to the board and doing it that way? Seems like Interware already included the adapter for you.

Desoldering through-hole parts with lots of pins is tough to do without damaging the board. The best tips I can think of are: - Use flux (like activated rosin) and good desoldering braid/wick. If you have crappy desoldering braid, it works a lot better with flux added to it :) - Use the biggest...

Odds are good that L12 is the same value as its neighbors, but you'll need something like an RLC meter to find out.

Yep, the plastic should be the same. The main thing I check is the gold plating; the Mill-Max is 30.0µin (0.76µm) thick, and the Preci-Dip is only 29.5µin (0.75µm). So you are getting 0.01µm less gold on the Preci-Dip part, but saving $4. I wonder what the margin of error is on that measurement ;)

Thanks @joevt, I always appreciate your insights. I need to sit down sometime and learn about PEFs, NDRVs, MKEXTs, and the lot, but I'm typically in too much of a hurry and too quick to bust out the hex editor or the soldering iron when there are more elegant methods available (and sometimes...

Those are nice, but expensive. There's a Preci-Dip part that's $4 cheaper and should be of equivalent quality. https://www.digikey.com/en/products/detail/preci-dip/110-83-964-41-001101/4093500

Thanks. Yeah, since there are so few boards out there with the SOIC-8 footprint, this may never be an easy PC-to-Mac conversion accessible to anyone not comfortable soldering under a microscope. It does open up the possibilities for new custom PCI cards though, perhaps multifunction ones. I'm...

I had the presence of mind to take a picture of the XRack board after removing the flash chip, before installing a PLCC socket. ID3:2 are floating, and ID1:0 are connected to something. I will poke around a little more and compare to the PC card when I have a chance.

Here's how a working card shows up in OF: Note the difference from this post. cc97 and aa01 seem to get into subsystem-vendor-id and subsystem-id from the AT93C46 somehow, and this seems to be important to the card actually working.

I was able to make some progress on this thanks to @opualuan generously loaning me his XRack card. I dumped the ROM and attached it to this post. It's only superficially different from the Mathey ROM; just the names are changed, everything else is the same. The contents of the AT93C46 are...

It's almost certainly ADB, since ADB trackpads continued to be used all the way through the G4 models.

Very cool!

Hi @Ivan Holmes, I think I actually have what you need! I bought a 500MHz TiBook logic board on eBay a while ago to harvest its Uni-North and KeyLargo chips. I also removed the CPU and cache chips, but I don't need them. I can't guarantee that the parts will be functional since I bought the...

Haha, I wrote that page a long time ago :D The information there is correct, but not comprehensive. There's a Digital Audio schematic on MacDat, but I have never seen a MDD schematic, so I do not know if there is a difference.

Yep, that's my understanding also. I'm not aware of a difference in Apple's implementation between Quicksilver and MDD G4s, though, but perhaps there is one that explains why this card is not backwards compatible.
