old Macs and 68pin hdd with adapter

[CharlieFrown]

Hi, 

I got this perfectly working 9.1 GB scsi hard disk that came with 68-50 pin adapter, used to work fine in Amiga 2000, which is ancient computer. Is there any chance I could get it working with SE/30 or Plus? Anyone tried that before? I am okay with using max 2 GB partition in old systems. 

BTW the hard disk has a lot of jumpers, but none of them lets me control the parity...

You might have to use an external terminator on your SCSI cable. My SE/30s all seem to be picky with 68pin drives and adapters.

Seconded, I had to use an external terminator to get my SE/30 to talk to a 1GB IBM drive. I believe it could be a sign that the Bourns filters on the motherboard are marginal, but I’m not sure.

But yeah, try adding a terminator if nothing else seems to work.

Yes, it usually does work with 68 pin drives (although 80 are a crap shoot). I do have a few IBM 4.5 gig 68 pin drives that will not work but those drives won't work in most systems.

I also use a terminated cable when throwing a 68 in an old Mac. Here're some pics of that in an SE: https://68kmla.org/forums/index.php?/topic/28013-my-macintosh-se-that-was-damaged-in-shipping/?p=299807
