In article <54811.659833076@atronx.ocug.on.ca>, rwm@atronx.ocug.on.ca (Russell McOrmond) says: >(Specifically, anyone know what is stored in location $16? In $217 and $218?) The memory from 0 to $400 is the interrupt vector area, and a map may be found in any 68000 book. Most locations are not really used for anything. The only location defined by the operating system is location 4. The addresses you mention are pretty much unused and unuseful, so are a result of program bugs. Typically the only writing that should occur is by debuggers and similar programs, or by programs taking over the autovectors (which Commodore docs say you shouldn't do, but some people do anyway. Usually quite harmless). Hope this clears things up a bit. -- Dan Babcock
