### C-One

The C-One is a single-board computer created in 2002 as an enhanced version of the Commodore 64, a home computer popular in the 1980s. Designed by Jeri Ellsworth, a self-taught designer, and Jens SchÃ¶nfeld from Individual Computers, who manufactured the boards themselves, the C-One has been re-engineered to allow cloning of other 8-bit computers.

13. Given a diagram F : JC, a cone consists of an object N of C, together with a family of morphisms ψX : NF(X) indexed by all of the objects of J, such that for every morphism f : XY in J, $F(f) \circ \psi_X = \psi_Y$. Then N is the vertex of the cone, whose sides are all the ψX indexed by Ob(J) and whose base is F. The cone is said to be "from N to F" and can be denoted as (N, ψ).
«Let J be an index category which has an initial object I. Let F be a diagram of type J in C. Then category C contains a cone from F(I) to F
«If category C has a cone from N to F and a morphism from M to N, then category C also has a cone from M to F
