The 12" DOS card should work in any PCI PowerMac. I don't recall anything "special" about it. The entire line of "DOS Compatible" Macs were just machines that came with the card pre-installed from the factory and a case badge.

"Far East only" indicates that there was some legal issue back then, which is probably the reason for that statement. Or maybe the PR166 card got no FCC/TÜV approval for the rest of the world. ;)

Any Idea, why 7300 is not mentioned for the P100 12" card?

No idea. The 7300, 7500, and 7600 share the same mainboard, so there should be no difference. Case is the same, too. Maybe the 7300 was sold with a too weak PSU. The P100 card certainly draws more power than the newer P133 one.

I don't think so.

Here is the Win30 Driver, but the download does not work. Any idea where to get it?

Kids, 82C450 is very, very ancient..
Looking for 82C451 or 82C441 might be more promising.

Here's the driver disk for 82c451.

As for the 82c441, just use the included Windows 3.0 driver.
Select "QuadVGA, ATI VIP VGA, and 82C441 VGA" in setup, as described here.


One of these drivers should work with 82C450.
It's not like its successors and predecessors were completely different designs, after all.

I know nothing about the technical details, but I recall seeing a video many years ago about someone using an add-in card to run (I think) x86 CP/M on an Apple III. I don't remember where I saw it, because this was during the pre-YouTube internet dark ages back when you had to install RealPlayer to watch online videos the size of a postage stamp at 3FPS. :-P

Microsofts Z-80 SoftCard ?

I recall, there also was one for the IBM PC, too.

I know that the 450 is indeed ancient and therefore relatively slow. The vesa-driver does make dos-slideshows possible (pulse sun/wild) and also dpaint3.0 with vesa up to 800x600 in 256colors and 1024x768 in 16colors (only 512k)
But it works and the win31 driver works just fine in 640x480@256colors.
I have to check out the win30-driver you described above. Would be nice if Win30 works too with 256colors.

Does someone here have experiances with the orangepc620 card?
I put mine in my G3-Desktop but my K6-III 400AFR always is detected as K6-III/256 Mhz.
If the jumpers are correct on the card and on the orangepc-faq. it should run on 66Mhz FSB with Multi 2x. The K6-II interprets the 2X as 6X so 6x66=400. But I always get 256Mhz...strange...
