#MAC ERROR CODE 50 PLUS#

Motorola 68000 instruction tests for an overflow condition, and displays this An overflowĬondition results if a generated number is too big for its allotted space. Larger the number, the more space is needed to represent the number. This error indicates that the number tested isn'tĮach number stored in a computer is given a certain amount of space. Programmers can use an instruction in the Motorola 68000 to check if a number Sometimes a programmer puts these in as debugging aids, and then forgets This error results if the microprocessor divides two numbers, and the divisor In its vocabulary, you see this error code. If a computer tries to execute an instruction that isn't The computer has a specific vocabulary of machine language instructions Since that's a 50/50 proposition when running random code, this one shows So, when the microprocessorĪttempts to read or write a word or long word at an odd address, you see thisĮrror. But it mustĪccess a word or long word at an even memory address. The microprocessorĬan access a byte of information at an odd or even memory address. The Motorola 68000 microprocessor can access memory in increments of oneīyte (8 bits), one word (16 bits), or one long word (32 bits). Reporting the wrong error or having hardware problems.

If you see this error on a Macintosh Plus or SE, it's Tries to access one byte beyond the total bytes in RAM, it actually accesses You should never see this error on a Macintosh Plus or SE, because address references One or more bytes beyond the total number of bytes in RAM, you see a bus error. If one of these computers tried to access This means the computer tried to access memory that doesn't exist. Of Macintosh memory structures, and familiarity with the application itself.įixing it usually involves recompiling the source code.

Instead of displaying an error code, the system translates the code to the appropriateįinding out what's wrong involves use of debugging tools, intricate knowledge Starting with System 7, errors are displayed in a different fashion. An application can forget to check an error code.Ī Macintosh usually crashes with a system error code while running under.The stack can dip into the heap for just a few cycles and not be caught.These are examples of some problems that may occur: Problems a user encounters can be equally complex.

You can use them to interpret what is happening when your Macintosh gives these errors.īecause the Mac OS is a sophisticated, complex operating system, the This article explains what some Macintosh system errors actually mean.
