SGI IRIS graphics have a handfull of either 2901
or 2903s in them (not
as the geometry processor, but in some sort of control function)
Main processor is the 68020 or 010, though.
You could find 29xx logic in the occasional hard disk controller too. IIRC, Intel used their own 3000-series bitslice to do
their first multibus
floppy controllers...
Certainly the double-density controller in my MDS800 is 3000-based. But
the microcode is not given in the manual.
