Do you have a record player or turntable of any kind? If so, all you need is a special little box that you plug your turntable into via the phono leads, and then plugs directly into the line in on your computer. One of these phono/line converters can be bought for around 30 quid (I actually have one I'm able to sell if you like?) Then all you need is some free recording software and you're away.
If you'd like to know more, hit me up on
