Can anyone tell me if my old Canon 300TL flash is compatible with my Canon 60D DSLR camera. Thank You

Actually, if you don't get an answer here (I'm not familiar with that flash) You can always look up the trigger voltage, then check to see the maximum safe trigger voltage of your camera in the manual, and then you will know.

The TTL pins should all be in the same location, so it "should" talk to each other, but trigger voltage is what gets you into trouble. If you can't find the info, get an off camera radio trigger, that way, if the flash does have a high trigger voltage, at least it will just kill the receiver, and not your camera.

Check your EOS 60D manual. I believe the standard text in the manuals reference that Canon TL-series speedlights can be used, but with no control of the light output. The flash will flash only at maximum output and the photographer much adjust the exposure via the camera controls to account for the light output from the flash.

Here's a site that lists many flashes and their tested trigger voltages: http://www.botzilla.com/photo/strobeVolts.html

The 300TL is listed as 3.75 volts and should be safe - doesn't hurt to measure for yourself though.

Voltage should be OK but if it only works in manual then there a lot of old flashes that would work that way. Many have auto mode which work just fine.
