It looks like you've got an FC124 and FC6206- I can't tell the difference between them right off hand- but either way- they're both good cranksets (with the 6206 being way better than "good")
Good call, I'll take a look tonight and see what I'm dealing with. I'm also debating rotating the biopace rings based on a thread (elsewhere) that talked about getting 'oval'-like efficiencies out of your old biopace rings (I've also got a couple sets with the crosscut)
