The Power Mac FactorAs in our last video-card roundup, we found that accelerated video handily outpaces the 68040's unaccelerated on-board video but that the subjective difference
between one accelerated card and another that costs twice as much is only slight. In using the cards over a period of several months, for example, I was dissatisfied with the pace of only two cards, the $699 Mirror Tornado and the $1999 RasterOps Horizon 24. The other cards performed so similarly I could hardly tell them apart.
No matter how much emphasis you place on the occasional speed differences between the five cards, the equally fast performance of the PDS cards included with
Apple's Power Mac 7100 and 8100 calls the entire category of accelerated graphics cards into question.
Don't expect an accelerated video card to turn your graphics applications into speed demons. Upgrading from a Quadra to a Power Mac, for example, will have a greater impact on the speed of native applications such as PageMaker and Adobe Photoshop than will adding on a new graphics card.
Meanwhile, Macworld Lab found that the PDS card actually performed faster than any thirdparty card tested when using native Power Mac graphics programs such as Aldus FreeHand 4.0 and Adobe Illustrator 5.5. (Previous Macworld Lab results show that the PDS video was slower when using prerelease native software.)
Of the five cards tested, the SuperMac Spectrum Power• 1152 gets the highest recommendation, thanks to its relatively modest price and its quick performance (the fastest of the five cards tested). Certainly, the LeMansGT is every bit as good as the SuperMac card, and I even prefer many aspects of its software. But its high price makes it more attractive to graphics professionals who need sophisticated calibration options, and these options won't be available until Radius ships new software for its PrecisionColor Cal ibrator sometime in late September.-
The XK differs from the XP and X on one of the larger chips (lower right). Different brand, but I can't tell if it's the same type. The XP has a different kind of memory module than the X and XK. All three have different Firmware versions and slight differences in chips, jumpers, and overall PCB layout.

After extensive search I found out that rom V.2 will allow operation on PowerPC and compatibility with Mac OS 9.
Would anybody be able to program a chip for me with the V2 Rom?
I can't remember which ROMs have been uploaded, do you have a rip of the ROM you want to use? I could post you one at cost if the postage isn't too expensive? I'm UK based.After extensive search I found out that rom V.2 will allow operation on PowerPC and compatibility with Mac OS 9.

How long are you willing to wait? My dad has an AC card with what should be a version 2.0 ROM, but I won't see him for about 5 weeks (he lives on the far side of the country). I've asked him to bring his cards so I can rip the ROMs. Otherwise we could try Bolle's ROM, but I haven't tried it in different cards.Sadly, before reading this thread, I wasn't even aware revisions different than 1.1 existed, let alone materially have .bin dumps of them. Postage from UK for such a small part is not a problem, a letter envelope with a cardboard filler and a hole in the middle works well....

I'll need to get a ROM too, I only have 3.3V ROMs and these will be 5V.
Hey @olePigeon, do you still have these cards? Do you have a way of reading the ROMs on these cards?The XK differs from the XP and X on one of the larger chips (lower right).

As above, @Trash80toHP_Mini, do you still have these cards and are you able to rip the ROMs?View attachment 11546

It looks like my Red 24X is a later version than your Green 24X. Mine has the 2.0 ROM and it's in the lower position, hrmmm?
Interesting, My XP also has the 2.0 ROM, this is probably good news for you experiment. I ran the 24X 2.0 ROM on the 24XP successfully. It didn't work, probably because of the lower capacity RAMDAC. However it made a great grayscale 21" TPD card out of the 16" Resolution 24XP.
Jailbreaking the Radius PrecisionColor 24XP . . .
We'll have to check compatibility with OS9.x.x with these cards. I'm wondering if your X will do 9.1, even with the 2.0 ROM. If mine is a 24X at all. :?:
OoooooohJust came across this thread and haven't fully digested... I do have a 24X, but it has a 1.4 ROM IIRC. Perhaps more interesting, I also have a 24XP:

Looking at photos earlier in the thread I can see they're 128k chips, so the card has 1.5MB of VRAM. That's the difference between the XP and XK, same speed DAC, but the XK has 3MB. The XK does 24bit at higher resolutions I guess.Just came across this thread and haven't fully digested... I do have a 24X, but it has a 1.4 ROM IIRC. Perhaps more interesting, I also have a 24XP:
