68 pin SCSI in Amiga

[RiP]

My GVP A2000-HC+8 doesn't detect Hitachi 73GB SCSI 68pin
I used SCSI 68 Male to IDC 50 Male Adapter. I enabled TP/Force SE but they didn't help.

Weird as it should work fine! Have you checked the jumpers? Unit ID, termination, etc

Yes, enabled termination power, different ID and Force Single End jumpers but no luck.

Well, the adapter didn't work with Adaptec SCSI card too:

I'll try to find this next time:

If you decide to skip desoldering the onboard passive terminator of the GVP card, then you only need your cable to match the IDC2-IDC3-IDC4 configuration, and of course you skip using Term1. I'm not actually advising against this configuration, it should still work OK.

That's about it.

Well, my 68pin SCSI hard disk doesn't have TE but TP.
Then I tried this configuration but GVP/Adaptec didn't detect the 68pin SCSI hard disk:

{IDC1}GVP 50pin-----{IDC2}[high-byte adapter+my LVD drive]----{IDC3}50pin SCSI 4GB HDD+TE jumper enabled (I used it since I didn't have 50pin Termination)
