Pure spectulation follows. TTI supplied their own controllers for SCSI DDS tape drives. I used a variant on an 11/750. I don't recall using a special driver and it probably came up as DEC Tape drive look alike. I never tried to attach a disk drive, but if VMS will load a the DKDRIVER for it, it might work.patrick-j lists a lot of DEC stuff. They might know something. The card was listed as coming from a running VAX 4000 so I asked if they knew what the card had been hooked to in that running VAX. Might get an answer.
The one chip with the noticed about being licensed from DEC was interesting, too. Means it might be a KZQSA clone.

Much obliged.If memory serves me right, i have some kind of advertising paper "somewhere" lying around. In it is written that they sold only tape controllers.
I try to look after the paper the next weeks and get back to this thread...
So stay tuned ;-)
I have to agree.I assume they don't know anything, seems like most Qbus cards on ebay are being sold by surplus dealers who just buy the stuff and list it. Half of them refuse to list the cards with their actual module numbers and insist on only listing the PCB part number, which is completely useless.
I swear it seems like some of those companies don't actually want to make money.

I recognized the q-bus shape and a NCR5380 SCSI chip and 50 pin connector. That had to be some sort of SCSI host bus adapter!
Best $25 bucks I ever bid! It turned out to be a TDL-12. Emulates 4 RL02 disks Using a SCSI disk.
Meanwhile, they’ll also list a TQK50 for $900.Best $25 bucks I ever bid! It turned out to be a TDL-12. Emulates 4 RL02 disks Using a SCSI disk.
I would have paid more. The lame description cost them a LOT.

Maybe dump the ROMs and look for text strings?
