A project of [Space station Freedom](https://en.wikipedia.org/wiki/Space_Station_Freedom) had a long evolution and eventually ended as US segment of International Space Station.

For ISS we know specialisation of [pressurized modules](https://en.wikipedia.org/wiki/International_Space_Station#Pressurised_modules).

**What were purposes of Freedom station's pressurized modules?**

I found this NASA video:

But this video is not detailed enough to deduce the purposes of pressurized modules.

Interesting moments from the video:

1) Cupola-like observation cabin looks in zenith, not in nadir like on ISS.

2) Interiors of pressurized modules have many similarities with ISS. But there is much more messy in ISS modules, with lots of wires and equipment at walls.

3) [Glovebox](https://en.wikipedia.org/wiki/Microgravity_Science_Glovebox) at Freedom station

4) There is nothing like [Quest airlock](https://en.wikipedia.org/wiki/Quest_Joint_Airlock). **What EVA airlock was planned for Freedom station?**

Because the desing of Freedom station was changed many times, an answer about at least one configuration would be good enough.
