Hmm... It looks like that doesn't work. The Drawing Board didn't directly open the old files and I couldn't find a way to import them.
I did get MML to load the output of TDB. Doing so requires saving the mech as XML instead of the standard TDB format. Opening it seems to have mostly worked correctly, although jump jets didn't load correctly in MML (I see them in the XML, so it looks like the problem is on the MML side.

Looking deeper into this, it looks like Mechworks is a 16 bit program, as it was made for Win 3.1. Up until XP, you could directly run it. In Win 7, you could download XP compatibility and run it. For Win 10, it looks like I'd have to dig up an earlier version of Windows (and its license key) and run it in a VM. I'm not willing to put that much effort into this trip down memory lane. :)
If anyone has other suggestions (or knows about something I've missed in TDB), I'm definitely interested. These are my old mechs from various campaigns going back to high school. If I can get the mechs into MML, I'm willing to put some effort in, as then I'd be able to use them today.
