Correction.  It might be one of  ZLXp-Lx products from DEC.
Strolling google scoped out a rather amusing tip. (A bit surprise for me)

This report mentions a company named Dynamic Pictures, Inc.

It's significant to see the three company names there.  DEC wanted it for
Alpha NT graphics workstation.  NeTpower; it's a company founded
by ex-MIPS Computer engineers who intended to continue MIPS NT
products.  NEC led MIPS NT development inherited from
Packard-Bell.

As I kept a distance from high-end PCI graphic market I did not know
about the company was bought by 3DLabs in 1998.
