Hi guys,
I've recently aquired a couple of Commodore 64's and was wondering if you could tell me about them :-)

The brown one was in a local paper advertised as FREE to collector. So I drove 30 miles to get it and gave a nice old couple a fiver anyway, without even opening the big old cardboard box that they handed to me.
For the white one I made a donation of £10 at charity shop yesterday.
1. Why do they look so different?
2. How old do you think they are?
3. Are either of them rare or valuable? :-D
4. Anything else you can tell me about them?
The white one is boxed like new but is missing a cartridge that is shown on the rear of the box with pictures detailing the games Flimbo's Quest, Fiendish Freddy's Big Top O' Fun, KLAX and International Soccer :-(
Thanks
