This link claims the HP-42S lacked an electronic input facility specifically so that it would be accepted for use by "various examination boards." Is there any truth to this? I have read that the originally planned HP-42S (or 42SX) input capabilities died on the drawing board due to repeated project redirections and cost-cutting directives. But this is the only time I've seen a claim that it was driven by exam board constraints. I'm skeptical....
