Starport
A= Full starship yard, refined fuel, TAS, banking, +4 broker, High Port
B= Repair yard, Boat Construction Yard, Refined fuel, Banking, TAS, +3 broker, High port likely
C= Limited repair, Fuel, TAS, +2 broker, May have a high port
D= No repairs, hangarage potentially available, has a chandlery for LS/food/fuel. +1 broker
E= No broker, but customers and a beacon. May have mail service in the form of a parked type S. Essentially, a designated spot where people expect interstellar commerce
X= Nothing at all.
G= Same as B, but not the main port in system
Size= 1000 miles (1600 km) diameter per point

6-7 Standard (0.75 to 1.25 bar)
8-9 Dense (≥1.25 bar, but still breathable)
A unbreathable but not otherwise hazardous
B hazardous and unbreathable. protection required
C corrosive - defeats vacc suits and battle dress in 2d6 hours.

6 WW II, first computers capable of jump calculations can be built... but first jump drives not doable, so this is the "we found a drive and can make it go" tech level.
7 'Nam era (late 1960's early 1970's) Gravitic Maneuver Drive can be built. Ship's turret missiles.
8 Supposedly 1990's; in practice, looking to be the 2020's. First gravitics supposed to appear. Fusion.
9 Jump Drive J1, practical gravitics, ship's turret lasers
A artificial gravity and inertial compensation; extended 3G+ trips possible
B J2, practical battle dress, man portable plasma guns
C J3, repulsors, practical clones, ground vehicles starting to be replaces with cheap gravitics.
D J4, tractors, meson spinals and bays, limb regrowth
E J5, first experimental AIs
F J6, computers still fail the turing test most of the time. 50T Bay Meson Guns practical

population multiplier. Multiply the above pop by this digit to get pop to one significant digit.
Planetoids - number of non-mainworld asteroid/planetoid belts
Gas Giants - number of gas giants (in T5, it's possible for one GG to actually be coded as the mainworld, if so, it would be number of non-mainworld GG's. Note that a GG mainworld would be a referee fiat situation.
