guys talk to me,

what do you think about this? anyone done any testing with it?

Seems really expensive for an adapter. Also, would it not have the same termination issues as the others that needed those extra resistors?

68 pin Wide SCSI drives are getting about as hard to find as 50 pins these days.

The nice thing about the SCA drives is that there were *illions of them in servers, and since they were "server-class", they tend to have much more longevity than the "consumer" drives.

But - if you've got a stash of wide drives, knock yourself out :)

I have a 68 to 50 pin in-line adapter. No offset like that one, just a black block with 68 pin on one side, 50 on the other. I never had tried it though so I dunno what it does.

Yep, I only had one that's got active termination, but I 'Bayed up some that Chinse Costume Jewelry that I love so much for a lot less money than that, IIRC. I'll see if I can dig up a link from my purchase history, they're exactly what techknight just described.

In the meantime, it's might actually better to buy those the high quality internal Ultra cables with the terminator hanging off the last drive position. I just hooked the terminated end up to an UltraSCSI Barracuda, the second position up to one of my very, very inexpensive, unterminated SCA->internal_68_pin_+_50 pin adapters, and plugged a 50 pin Ribbon Cable into that. It should work better than the unterminated adapters I bought.

The terminated 68->50 adapters I saw on eBay were in the $50-$100 range. 8-o

As long as it has "upper byte termination" it will work in a classic mac with 50pin bus. The drive needs to be jumpered for single ended mode (most are set to LVD by default) and you will need to terminate the SCSI chain with another device or pigtail active terminator.
