    Radeon 9000 Pro AGP Flashing

    Thanks for the data point! It has the 3.6ns RAM, so it should be a perfect match for the publicly available ROMs with 275MHz clock speed.

    Thanks! I think the Mac 7500s all have QFP RAM, so these three are all 9000s. Looks like all are 64MB cards. The firmware from all three would still be interesting. I believe both copies on The Mac Elite must have come from a hynix -36 card like the one on the right, because the RAM clock speeds...

    Does anyone have an ATI Radeon 9000 AGP card that looks like the first one in this post, with the hynix -33 RAM chips? I believe they came in MDD G4 towers, and there was also a retail version. I'm looking for a copy of its firmware, but I can't even find one for sale anywhere.

    G4 1Ghz Sonnet Encore Power cable

    The Molex Mini fit Jr. pins (Sonnet card) are rated for at least 5A each, and there are three of them. A single AMP Mate-n-Lok (4-pin internal drive connector) pin is rated for 11A. Granted, that 11A comes with a 30C rise, which is a little uncomfortably hot. Realistically, the G4 is not...

    PowerMac/Performa 5xxx NOS tube swaps directly into slot load iMac G3

    Wow! Dare I ask where you got the 5xxx CRT and how much you paid for it?

    Radeon 9000 Pro AGP Flashing

    Did a little more searching; these 9000 cards are a real crap shoot. There are at least 4 variants. Here's a 64MB card with 3.6ns Hynix RAM (that's 275MHz): Here's a 128MB card. It also uses 4ns Samsung RAM:

    Radeon 9000 Pro AGP Flashing

    That's kind of what I'm suspecting. I thought it would be a slam dunk because my card has the same RAM as at least one of the Apple variants I can find pictures of: There was also apparently one with 4ns Samsung RAM, which should only be good for 250MHz: I don't think that either of the ROMs...

    Radeon 9000 Pro AGP Flashing

    Thanks guys. Yeah, cards from this era can be somewhat fragile, especially the BGA parts. More reason to try to preserve them, I guess. I admit, I've been too lazy to install a version of Windows on the old P4 motherboard I'm using to test AGP cards. I just booted it into DOS and ran it though...

    Radeon 9000 Pro AGP Flashing

    I was buying stuff from Japan a while back and threw in a cheap Radeon 9000 Pro AGP card. My half-baked plan was to steal its 3.3ns RAM and try to build the world's fastest Radeon 8500. I'm not up for that tedious (and probably pointless) of a project right now, but I wanted to do something with...

    Do any current low-end laser printers play well (or poorly) with older (post-Classic) OS X macs?

    I have a Brother HL-L3230CDW. It's been great; rock solid reliable, reasonably priced consumables. I just tried connecting to it with my Quicksilver running 10.4.11. It was detected immediately via Bonjour in the Printer Browser utility. I tried the HL-2460 series CUPS v1.1 driver and it quickly...

    Quicksilver Power Supply Recap

    I've been trying to kill the high-pitched whine/hiss in the Rev. B power supply, correlated with CPU/GPU load, for a while now and have not been successful. In addition to the recap, I tried swapping the Rev. E fan control board into the Rev. B. It works fine, but no noise improvement. I...

    Any interest in 16MB Mac IIFX memory modules?

    I wonder if this was an OpenClaw thing? The Internet is a weird place to be right now.

    Sonnet Crescendo G3 vs. G4

    I just picked up a Sonnet Crescendo G3 300/1M on eBay because it was cheap enough and seemed like it would be fun to play with. This is the "big" card that Sonnet also used for G4 upgrades, vs. the smaller design that appears to have been for G3s only. I noticed that the G4 version has two...

    Testing with another PDS card would be a good idea. Unfortunately both the machine and the card are suspect at this point.

    ATI Radeon 9250 PCI cards, converting from 64-bit to 128-bit and other details

    I'm not sure. I think it would be worth opening another thread if you can't figure it out. Honestly, most of the fun for me in stuff like this is getting the hardware working; once I do, I tend to lose interest and move on to the next thing I want to try to get working...
