Zitat von Mouse <mouse at rodents-montreal.org>:
marked LSI LOGIC (obviously a maker's logo) and is
otherwise labeled
LR33000MC-33 / MIPS CTRLR / WB33391 / NNH 9250* / 5C1321WUFBA where
the * represents an approximately equilateral triangle, oriented so it
looks like an over-wide capital delta.
Looks like the RacerX from LSI (r3000 core with a graphics co-processor)
