I recall the days when the circuit diagram either came with the user
manual, or the makers were happy to send it to you upon request. Indeed,
when you could get technical advice with no problems via phone or
letter.

Or, in the case of certain Philips cassette recorders, the circuit diagram
was tucked in the space between the motor and the outer case - out of
sight of the casual user but easily accessible to someone like me who
loved opening things up just to see what made them work.
