Curious. Besides the manual, "cash box and score cards" the latter two you could help him with.
The important thing. Does he play the games ? Does he like the games ?
If your Father likes the games, the three things aren't important then. And if you buy a Spooky pin, your Father has Charlie's phone number. And Chris at King Pin Games recently started helping with tech support. So a manual may not be that important should your Father need help, with Charlie and Chris on the job.
