I'm building this at TL-13... and going through NASA documents on
TL7/8  space shuttle and ISS for inspiration and thinking things
through
One of the biggest simplifications is saying that TL13 has
electrodynamic metals rather than hydraulics... because of all the
huge support chain to make hydraulics work
Shuttle Hydraulics needed APU ... which needed fuel cells running and
needed its own reactant supplies and needed lots of heat dumping and
then controls and monitoring for all that and another layer of
controls and monitoring on the controls so you could switch to
redundant control network. AND then redundant APU and everything else
again.

Gravitics and M-Drive are huge simplifiers too - just getting rid of
RCS and making it part of the M-Drive greatly simplifies things
