Yep 1541. I couldn't remember it's number. I thought the code in the magazines were in a form of BASIC. I could be wrong though. It's been a long time. I remember it could do BASIC because I played around with creating my own lottery game and that was in BASIC. My favorite game was One on One: Dr. J vs. Larry Bird. I remember everybody thought those graphics were to die for. And you could break the backboard! Those were the days.
