What @BSZ says is correct though: the MOS 6529 has open-collector-style output, so you might not get very good results. In that case some kind of buffer IC could be interposed. Maybe even a simple 74x244 or something like that.
@MMS: 1% resistors aren't that expensive, see this for instance.
0.25% and 0.1% are significantly more expensive, but still affordable. SMD stuff is probably even cheaper.
Anyway @Spektro here already has a Covox, he's just looking for a way to connect it  . These considerations are more useful for the DIY projects I linked earlier.
