Version numbers are an artefact of my early development. Packaged programs are up for Beta testing.
Some debug code is included but commented out.

Intended mods:
ComputerCraft (computacube)
SilkTouch Spawners
Roguelike Dungeons
Tinkers' Construct (optional)

Configuration variables are meant to be edited by end-user to suit each turtle's conditions

Build a regular dungeon spawner, only with spawners silk touched from a roguelike dungeon.
All testing so far has been with skeletons, but Nitro Creepers tend to destroy the testing aparatis if they ever sneak in.
Tinkers' Construct channels work like 8-way conveyor belts in the Nether to gather mobs, and work as a mob elevator.
Programs are designed to be resistant to crashing and chunk reloading

Install each program onto turtles as "startup"

TurtleGrinder is designed to work beside copies of itself with stone pressure plates for mobs to detect mobs. Containers above and below (recommended double chests with hoppers leading into sorting turtles) take the crudely sorted output.

TurtleSort has two jobs. It can work as a 6 way hopper with a full stack capacity if you configure both the accept and reject to the same spot. Fill excess inventory slots with items with redundant acceptable items or items you don't expect to come through the system.

LootRepair fixes items and passes bad items along. They can be chained.
