As a former BBC Micro (Model B) owner that is a great site.
It was my first ever piece of games hardware and I got it on my very first day of School, aged 4, pre-dating my GameBoy by 2-3 years and my SNES by 4-5 years.
So many games I remember as a kid.
Literally just sort it by "Popular" and you'll see some of the classics I grew up with.
Chuckie Egg - Still might be in my top 10-20 games of all time.
Killer Gorilla (Donkey Kong clone)
Space Invaders
Mr Ee! (Mr Do clone)
Repton 3
Starship Command
Cylon Attack
Imogen
Great Britain (A political management sim where you become the government of the day)
The BBC might not have had the broader commercial impact of the other 8-bit Micros, but it was a beefy bit of kit and has some fantastic games. Especially the ports and clones which are often as close to the Arcade as you could expect back then. It would have been interesting to see how it faired had it been a bit cheaper.
I can only dream of the stuff Codemasters and other devs could have done with it and as a kid I would have killed for a port of one of the Dizzy games. We did get some of the Ultimate games though.
Best part was when my Dad would come home with a new floppy disk he'd gotten from a workmate loaded with new games to play.
I really want a Model B now. To eBay!
EDIT: Yeah these aren't particularly cheap anymore.
I'd still like to get one though.
