   No, _this_ is a KZPBA:

6800   B0 PKB:    9 Qlogic ISP1020 SCSI-2

A KZPCA uses an LSI/Symbios 53C895 chip, however.  (The Qlogic
card uses an ISP1040 chip, but VMS tends to call it a 1020.)

   That would be unusual, but it would be a welcome change.

   What's a "name brand" SCA adapter?  I've found that cheap
Chinese junk is pretty much cheap Chinese junk, no matter who
sells it.  I buy my 68-pin adapters on Ebay, too, like the two
("new") ST373207LC drives I just bought for $31.  For that
kind of money, I can afford a few mistakes here and there.

   I _have_ found that the 50-/68-pin SCA adapters which I had
been using on my oldest junk systems did not do well in a
faster Ultra SCSI environment.  68-pin-only adapters have
worked fine.  (And, at one-inch high, they fit better with
one-inch-high disk drives, too.)
