V5 was the cutoff for DEQNA, specifically it was DEQNA is unsupported
and DELQA was supported. That really ment that if you ran a DEQNA
and had problems with it they would tell you get a DELQA. It'also meant
the code to run DEQNA was still there and it should work but to expect
no software updates for that device and that device did run at reduced
performance. I don't believe the driver itse;f was deleted till later
Also the DEQNA was prone to failure, so if the system doesn't see it
it may be cause it is dead.

V5 or later works in 6 but very poorly. It should not be hard to
find working ram to increase that.
It could also be the over the top connector has failed.

That would tell us something.
