I recently took delivery of a $9 computer, called C.H.I.P, a kickstarter project from 2015.
I opted for Pocket CHIP, a Gameboy-esque case that provides a full keyboard and touchscreen interface along with a battery.
I wanted to have a quick play about with the kit, right now I am busy with projects but a g33k needs to g33k!
So I opted to load up Doom 2 using the prdoom application. Yes I legally own the Doom 2 WAD. I bought the Ultimate Doom CD from a charity shop :D
Anyway, quick Youtube video of me sucking at Doom 2!
