Not quite moor this Batman show had a Batgirl before there was a robin, and barbara gordon is older than dick grayson in this show
you're right... I was a bit hazy when I posted that.. I was half cocked remembering some of the stuff that was considered canon prior to Zero Hour, i.e. Miller's Year 1, Barr's Year 2, and Dixon's Year 3. But two retcons later, and they are now a moot point
But I did actually like the fact that they waited to bring Robin into the series!
