Zx spectrum 48k , donkey kong and chuckle egg. PC first game ghost recon in around 1999.
I presume you mean Chuckie Egg? I don't know why but I get a warm feeling whenever I see that game. We had a bbc micro and I can remember my mum showing me that game as something she played when she was young. That and Mr Do.
I can't remember the specs but the first games I played on PC were MSDOS games like fatty bear's birthday surprise and Put Put goes to the moon etc
