If you dont want to wait for the C.H.I.P. to become available again, a Raspberry Pi Zero should be able to do everything necessary here. It is about $5, can run linapple-pie, and has composite video pinout.

Pocketchip on hold, the rest "contact sales".

Honestly wish someone would clone the pocketchip for use with the PIZeroW.

Its so underpowered though, other Allwinner SBC vendors already have H2+to H5 boards for cheap (eg: $6.99 for an OrangePi Zero), even an H2+ chip has 4x the cores at a similar clock as the CHIP.

This market moves so fast that you have to release new products 1-2 times per year to stay near the top in performance in a given price band.

C.H.I.P.'s claim to fame, as far as I'm concerned, is that they're the first kickstarter I bought that delivered on time.
