I found it. It's on page 6 of the First Missions document:

When I first read that each turn had 32 individual movement opportunities, I was like *what?!*

-- now I see it's basically a matter of counting through and asking who does what over and over again. In the mid 90s I ran a ton of the SLA Industries RPG (basically a dystopian sci-fi splatterpunk setting) and that game had each 3 second combat round broken up into 5 phases of 0.6 seconds each. Depending on your dexterity store you acted in different phases like maybe 1,3,5. You could also take combat drugs that changed the phases you acted in.

I've decided to scratch build my own miniatures in the end. I already have some starfleet appropriate space stations and asteroid installations in 1/7000, so my options are shapeways and scratchbuilding.
