Orac, under Avons instructions took over the System that built the liberator, Orac had them build a large fleet of them for the rebellion, plus a few more for Avon himself.

Avon had clones meet the federation troops, Sevalan had thought she eliminated them, Orac had copied the clone technology when Sevalan tried to clone herself.

Avon had a laugh

Roj Blake then led the attack on the Federation using over a million Liberator class ships, the original design modified by Orac.

Servalan gets teleported to a remote lonely isolated planet with no other lifeforms

but a teleport malfunction creates two copies of her

they spend the rest of their lives trying to kill each other

Avalon has another laugh

Orac now with sufficient information to take complete control of a black hole teleports itself into the black hole, Orac now becoming even more powerful, the black hole then disappears

A distant “Goodbye, Avon” is heard on the Zen computer

Geez, we haven’t had Blake’s Seven on Australian TV since 1981.

May be my fault. Mr buffy and I are currently watching the full 4 series. We are up to Series two, episode 5. I have reported here. So that must have brought a reaction.

Yes, part of it is your fault

I have linked 5 episodes into the alternate ending

episode “Blake” (clones were killed, not B7 crew)
episode “Orac” A powerful supercomputer that can read other computers using Tarriel cells, Orac also has telepathic abilities
episode “Redemption” featuring the System which built the Liberator
episode “Dawn of the Gods” where Orac studies a Black Hole
episode “weapon” Clone technology copied by Orac

I was assured by an ABC staff member twenty-something years ago that they would never ever repeat it.
