How I managed to end up with these I have no idea. But I was wondering if they were anything special. Kinda doubt it...
2600 - Outlaw, Centipede, Yars' Revenge and Breakout
7800 - Tower Toppler
Thanks for the help!
The 2600 games are common as muck. If you're lucky, maybe £1 ($2) each loose, or upto £3-£4 complete & mint.
