This is an Elite3D M6 24-bit *vertical*-UPA frame buffer.

FYFI, the Sun UPA graphics adapter connection comes in two flavors known
as vertical and horizontal UPA.  They use the same basic signalling and
communication protocol, but over different connectors.  Vertical UPS, as
in the one you have, looks very much like a PCI64 card.  "Horizontal"
UPA (referring more to the card than to the connector) looks much more
like an SBUS card in which some of the pins in the connector are
replaced by elongated "blades".
