What are some good examples of recent buggy whip [manufacturer] obsolete items/jobs?

This guy claims to have some cheap slide rules for sale for under $100.

Thanks!

(I think his website is as old as the slide rules!)

Amusingly, from that website:

Slide Rule Express Service! Order a rule today and it’ll ship tomorrow. No more waiting for checks to arrive and then to clear. Just tell me that “the check is in the mail”, and I’ll just take your word for it! This seeming ridiculously naive policy is possible because of the extremely low observed correlation between an appreciation for slide rules and a tendency to stiff people.
