Here I am, not referring to a data book, but generally, all the TTL counters that end in "90" are decade counters while the ones that end in "93" are binary counters.
(1) Assuming that this is a ripple counter with active LOW reset, you can insert a NAND gate connected to the Qd and Qb outputs so that when the counter tries to go to 1010(b), it be forced to reset.
(2) Often, the decade and binary counters of the same series are pin-for-pin compatible and you can just plug in the decade version in place of the binary version.
(3) If push comes to shove, there are binary-to-BCD TTL converter chips out there floating around somewhere. Again, the data books aren't handy right now.
