This is a question Redundant technology

Music on vinyl records, mobile phones the size of house bricks and pornography printed on paper. What hideously out of date stuff do you still use?

Thanks to boozehound for the suggestion

Voltage levels?
Corners are often cut with the voltage levels. According to Wiki the original spec (1969 or so) says the driver is meant to output at +/-12V and the receiver is meant to recognise signals down to +/-3V. I just measured my own equipment (fnar) and my USB adapter gives 7.74V but the PCI card in my desktop gives 11.46V.
