The kids TV show Bertha? From memory there was a factory machine called Bertha and loads of jolly characters. I think there was an asian gentleman that used to zoom around on a forklift truck muttering 'put put' or something.
The song was ace!!
Bertha, lovely Bertha, you are a lovely machine
Any anyone who works with you will know just what I mean.
Bertha, lovely Bertha, sometimes I thing you're a dream,
When we work out what you have to do,
You can always turn the goods out, always turn the goods out,
We can depend upon you.
Clicking in the day and flashing in the night,
Your computer is shining brightly,
Some people say you've a mind of your own,
And I think that's very likely, likely.
Bertha, lovely Bertha, sometimes I thing you're a dream,
When we work out what you have to do,
You can always turn the goods out, always turn the goods out,
We can depend upon you.
Ha ha! Just found a website, I was right about the asian guy, called Panjid!!
