Battletech - 8614 - Technical Readout 3050 (1990 Edition)

A major step forward for the BattleTech tabletop game, this TRO introduced a wealth of new BattleMechs, new technology and an entirely new unit type—Elementals, armored infantry brought along the invading Clans.

The first editions used construction rules that are (somewhat inaccurately) called "fractional accounting", where 0.25 ton increments were used. Later construction rules would only allow 0.5 ton increment, and at some point the designs from this book were upgraded to comply with the new rules.

As a result, the Timber Wolf (Mad Cat) had its Endo Steel frame and XL Engine mass increased by 0.25 tons each (to 4 and 19.5 tons from 3.75 and 19.25 tons, respectively) and to account for the mass increase, the ER Small Laser in the right torso was removed. Other designs may have received a similar treatment.

Visually, the newer, post-rule change editions are discernible by having the title printed in orange letters (instead of white) with the line "Warriors of Kerensky" in blue instead of orange.
