Which is why I always used to leave my EPROM programmer set for a
Vpp of 5V (back when devices used Vcc=5V and Vpp typically of 12.5V, 21V,
or 25V). That way even if I accidentally told it to program, nothing
would happen (unless the part was a 5V-only EEPROM).

However, the more recent EPROM programmers I'm using don't have such
an option.

Anyhow, there are lots of ways to accidentally damage a part, even if
you don't put it in an EPROM programmer and tell it to program.
