700,000 years after the invention of the Type 1 the people of Gallifrey agreed that a TARDIS could be used to safely participate in the Web of Time. However violations of the Laws of Time were (and still are) still possible.
Like the Types 15-29 this TARDIS had default exterior that is a silver-grey metallic cube 3 meters on each side. But it was the first equipped with a Chameleon Circuit. Development of the Chameleon Circuit began before Omega was lost. Technicians successfully tested the prototype for the circuit shortly after the Eye of Harmony was created. However the circuits were not installed as a standard part of TARDISes until the Type 30. This was done because lost timeships were creating legends and mythologies of monsters and gods among the lesser species.
Like other pre-60 types of this era, the Type 40 often developed faults
with its Fluid Links.
- First to be considered safe for chronoforming history.
- First to have a Chameleon Circuit
- Frequent fluid link failures.
- About 200 years after the birth of the Doctor the Mark II and Mark III upgrades of the Type 30 were very popular.
About one million years after the Eye of Harmony was anchored, Gallifrey began to enter into a period of stagnation. The Time Lords discovered Quantum Mnemonics. This science is capable of altering the nature of reality and probability, allowing one to reshape an the history of an entire planet. This form or reality manipulation was far superior to the block transfer equations used to create a TARDIS. Despite this, TARDISes continued to be constructed using block transfer computation. The Time Lords turned aside from the barren road of technology and abandoned experimentation of any kind. This cultural stasis would last more then a million years.
