Suggest you join LEM-Swap for buying & selling Mac stuff. http://groups.google.com/group/lemswap
After you join, post a WTB (want to buy) with your posted info.

"I have Adaptec 2940UW and Adaptec 2940U2W cards which work on my Blue and White G3 with SCSI drives."
Are these SCSI cards the same ones that were in your G3? The Adaptec AHA-2940UW and AHA-2940U2W are controller cards designed for use in PCs, whereas the made-for-Apple card is the AHA-2940U2B. Bootable controller cards must be firmware-based and not driver-based, because they must be recognized, before a driver could be read from any connected hard drive. A card designed for use in PCs won't function in a Mac, because its ROM lacks the correct programming. An unsupported, installed "PC" controller card may be recognized by the System Profiler, but that doesn't guarantee that the card will function. With a Mac-compatible controller card, you would be able to format the connected drive using Drive Setup, which is in the OS 9 Utilities Folder. You might find it useful to download the "PowerDomain 6.1.2" (pre-OS X) utility, that's designed for use with the Adaptec SCSI controller cards. Its "PowerDomain Control" lets you select certain options on the card.

Thanks to all for the helpful links. To Jeff, yes the Adaptec 2940UW and 2940U2W cards are the ones that worked fine in my Blue and White G3. I received the Power Domain software with the cards, but never needed to use it. When looking into the G4 thing a few years ago, I was told that the ATTO cards were the only ones that would work with Powermac machines that were made to boot in OS X. I passed on it because it was $400 at the time. My humble tests seemed to confirm that. Yet, if it's firmware based and not OS-based as you mention, I'm not sure if I know how to tweak that. I was hoping to hear that someone had a card name that they have used with a machine identical to mine with proven success. I've done several hours of research, but may need to continue at it, or call ATTO and hope for a different tech.

I looked at the boxes, and technically, they are Power Domain 2940 UW and Power Domain 2940 U2W. My understanding is that Adaptec put "Power Domain" in front of the card names for Mac-compatible scsi cards at that time.

I ended up buying an ATTO UL3S Ultra 3 SCSI card used and it's working famously in OS9. It's boots fine with drives running OS9. I got is used for $25 so it was a cheap bet. Just wanted to post my results in case others might benefit.
