I think, sadly, you're pretty well much SOL. Like a lot of other people, I had high hopes for the Choosatron project, and honestly thought this could be a fun machine, teaching children how to creatively write, allow me to write the occasional amusing (or not) story. However, like a vast majority of Kickstarter projects, I think it was overly ambitious and became too much for just one person.
I hope you're able to get some satisfaction and at least get a circuit board at the bare minimum. The rest of the stuff can be purchased online (the printer, keypad and power supply). You should find the case specs floating around somewhere here or at the Kickstarter page. Given that, it shouldn't be too hard to make your own arcade style machine. The circuit boards are the same, you just need to wire up a switch (for coin entry) and some tactile buttons for choices.
