Assuming it would be a largeish chip (at least 24 pins), none of the ones
you mentioned are present. Nothing from Intel, NEC, or WD at all.

There's an "AMI S2350P", and an "AMI S1062P", and an "AM9517A-4PC", an
"SY2128-1", a "FERRANTI ZN 1066E", three PIO chips, two CTC chips, a Z80,
and a Hitachi HD46505SP. Oh, and three ROMs or EPROMs.

All the rest is small-fry stuff.
