Thanks ! Shouldn't be called "Old" though, since it covers ALL the common markings right up to the newer 4+1 band markings on the newest 1% resistors. The old system most commonly seen was known as the "BED" system, which stands for "body, end, dot." The body is the first digit, the end, is the second digit, and the dot is the number of zeros following the two digits. Sometimes there was a second end in silver or gold indicating 10% or 5% tolerance. I always get a kick out of those who call the dot, or third (or fourth) band "multiplier." The color corresponds to the number of zeros you draw after the initial digits. Example: brown black orange, brown is 1, black is 0, orange is 3, so three zeros, hence 10,000 ohms. LOL ! I think some folks just like to sound all high fallootin' when it's really very simple.
