I have about 5 or so in storage, they worked fine years ago... Went from a couple of hundred mb to 4 gigs. If your really interested let me know and I can pull them out and look.
Concerning the converter to 68 pin scsi, it works fine here. I have a 3000 with a 10k Quantum Atlas and it works great. I don't use the 3k scsi, I'm using a warp engine 3040 for the SCSI though with PFS 3 (Not sure if that would make a difference?)...
I ordered the converter from a local computer store years ago, I can see what brand it was and if it's still in the market...
