Well, thanks for the help, I got it to work by starting at 30h and jumping into main. Thanks a lot!

I was thinking, since there has been some talk about FAQs and tutorials.. It would be real nice to have some kind of interrupt tutorial. Maybe an example on how to use it in a simple program? The faq info is good, but it doesn't provide example code, which I think could be really helpful for people just starting on the 8051, like me. For instance, maybe a description of the interrupt vector table?

Anyway, just a thought.. thanks again.
