  In particular, I recognize
 the 2910 as appearing on the Tandon SASI<->ST506 board in the Commodore
 D9060 and D9090 drives.  ISTR it's much like the 2901 but wider than 4
 bits - kind of an integrated building block for those designers who are
 more concerned with real estate than extracting every last feature the
 2901 has to offer, i.e., a compact short-cut. 
Nope, 2910 is a microprogram address sequencer for the 2901 series. 

There are, however, a number of "2901 with more bits" chips, however.  The 
IDT IDT49402/IDT49410A is the equivalent of 4 2901 slices (16-bits) + the 
apropos microprogram sequencer logic.  Cypress had the CY7C9101, which was 
similar.  WSI had the WS59032, which consisted of 8 2901 equivalents.  
Innovasic has the IA59032, which is an ASIC reimplimentation of the WSI chip 
and is still availible.
