Signetics also offered a clone of the Intel 3001 and 3002, as well as 
a control store sequencer unit, the 8X02.

I don't know if I'd consider the 181 a "bit slice".  There were also 
CMOS versions of this:  SCL4581, MC15481, HCL40181, etc.  And Moto 
had the MC9704 mW RTL 4-bit adder (though that's probably really 
stretching the case).
