Some of the programmers and computer interfaces and circuitry/schematics information found on this site and relating pages show direct interface to the computer external ports.
Since high voltages (>5v) may be present on the circuits it is very important to check you have wired the circuit correctly otherwise you may damage the interface port on your computer which may be on the motherboard.
I strongly advise you to use interface ports on plug in cards which can be replaced in the event of permanent damage.
