This is a Quadra 650 - 33MHz with Ethernet. Will have shipped with a full fat 040.Probably, but only Centris 650 have LC040 IIRC - Quadra 650 and 800 have full '040.
I'm trying to understand the signal termination requirements of the MC68040, and it seems Apple has done it all: I can't see any termination for A/D on the Q900 schematics, it's present but labelled "for 40 MHz operation with large buffer" for Q650/Q800 (which I'm trying to confirm are always using small buffers and no termination), and are always present/large buffers on the 840AV...
