WTB Replacement for one Qbus Dilog DQ614-s

As far as I can imagine from my tests, I have one Dilog DQ614-S which don't works. I tested it with a couple of 5.25 hard disks (one IMI, one RD52-A and one Seagate) all in the list of recognized drives. And, in fact, the disk can be accesed in some form (intermintent lights, etc). But when the format try to begin, the DL614P.SAV program answers me with one "UNEXPECTED INTERRUPTION VECTOR 000000" It could be the cables, with they work with other drive without problem. Now comes the real question: Do you have someone one DQ614 operative for trade which could be managed with the DQ614P.SAV program or another release of this one appropiate for the board ? Or eventually... Someone has or knows of another board which could manage one hard disk (MFM, ESDI or SCSI) as FOUR DLx disks as the DILOG DQ614 does ? Thanks. Regards. Sergio
