There are many ways to do this depending on what controller and connection is in use.

Thanks Nick, there's information here;

I don't believe I can flash it in situ so was imaging there would be a USB mechanism but there seem to be lots of variations as you say.

If its a ATTiny85 then it will need to be SPI programmed. Is the chip in a socket, or is there a 6 pin header on the board?

It's an 8pin DIL that plugs into an IC socket.

Ok, I have one of these

And a AVR Dragon, both will witha bit of wiring to a 8 pin socket probably flash the chip.

Thanks for your kind offer Nick but I'm getting a flashed chip sent to me from the US...
