Re: A86: Interrupt questions




I was looking at $66 and it is possible for that call to evade the exx and di,
reti instructions, if it reads the right value from the on port (port 3).  I
can't tell if it's forced to return or not: it may just have something do with
the checksum.

 Btw, what is the checksum?  How does any checksum work?
