Community Marketplace / Re: FS/FA Mac mini G4 Upgraded with SSD & Pre-installed Mac OS 9
« Last post by davecom on May 12, 2024, 07:20:14 PM »New listing is a 1.42/1 GB/128 GB SSD. It has a little bit of yellowing on the body but is otherwise in good condition. Mac OS 9 pre-installed and the auction has no reserve:

It comes with USB speakers, a period Apple mouse, and the power adapter.

Video Cards, Monitors & Displays / Radeon 9250 working on MacOS 7.6.1
« Last post by meow_mx on May 12, 2024, 06:20:24 PM »I was jealous of the MacOS 9 users having access to the Radeon 9250, and love an excuse to do something silly and educational. So, I hacked up Radeon 9250 drivers that work on 7.6.1!

My 9250 test card is fussy about DVI at higher resolutions (even more than my Mac Mini) which is a pity because System 7 at 3440x1440 looks really cool.

« Last post by ssp3 on May 12, 2024, 06:39:52 AM »Is 9500/9600 not an AV Mac even though it's very similar to the other Macs listed?
No. 9500/9600 lack the AV board with audio and video inputs and outputs.
They also have 6 PCI slots and, IIRC, two PCI bridges, each for 3 slots. Adaptec 2940 is a busmaster card, so that also could be a reason why there was different firmware for different machines. Since 2940UW worked in G4 machines too, I think AV firmware was a special case. I don't remember much, but I think that video in AV Macs went thru PCI bridge and SCSI cards had to "play nicely" with everything else on the PCI bus.
I also vaguely remember that at some point Digidesign required Adaptec cards to be throttled down for compatibility reasons with ProTools (or was it Avid?) systems.

« Last post by joevt on May 12, 2024, 05:58:55 AM »Too much work...What's the difference between the AV and the non-AV version?
How about double clicking "PowerDomain 2940UW v4.1 Readme"?
AV refers to the Mac (7300, 7500, 7600, 8500, and 8600). You can't use the non-AV installer on an AV Mac but can you use the AV installer on a non-AV Mac? What's the downside? Is 9500/9600 not an AV Mac even though it's very similar to the other Macs listed?

« Last post by joevt on May 12, 2024, 12:05:25 AM »The ROM resources use lzo1x compression.
What's the difference between the AV and the non-AV version?
The AV version has a 64KB (512Kb) Open Firmware PCI Option ROM (only one image).
The non-AV version has two 64KB Open Firmware PCI Option ROMs concatenated together. The second image is identical to the one in the AV version. Why would it need two separate Open Firmware images? What's the first image for? Does the card exist as multiple devices? Does it have a firmware switch? Both parts have the same device ID.
The first image is small and doesn't contain an ndrv.
The lzss compressor is unable to compress the second image to a smaller size but there's no point since the image is already < 64KB.

« Last post by joevt on May 11, 2024, 07:04:48 PM »The 'Rom' resource in the v4.1 flasher is 64783 bytes.The Rom resources appear to be compressed. There's a mention of lzo compression in the PEF of the datafork so I'll try that.
There's 'Crc' resource that probably should be modified as well as 'cfrg' resource. Maybe something else too.
Even if you manage to hack the flasher and squeeze in compressed ROM, then there's PowerDomain control panel, that, I think, changes card settings in the ROM and not in some preferences file. It is uncertain whether the CP will play along with compressed ROM.
v4.1 flasher is attached to the 2nd post.
