I'm using system 8.6, I've been getting type 1 and 2 errors. How can I avoid them?

Type 1 and 2 errors are the worst kind. They involve the bus (1) and the memory (2). They are always fatal.

ID=01 Bus Error
This means the computer tried to access memory that doesn't exist. You can get this error on almost any Macintosh. If one of these computers tried to access one or more bytes beyond the total number of bytes in RAM, you see a bus error. You should never see this error on a Macintosh Plus or SE, because address references that are out of bounds "roll over". This means if one of these computers tries to access one byte beyond the total bytes in RAM, it actually accesses the first byte in memory. If you see this error on a Macintosh Plus or SE, it's reporting the wrong error or having hardware problems.

ID=02 Address Error
The Motorola 68000 microprocessor can access memory in increments of one byte (8 bits), one word (16 bits), or one long word (32 bits). The microprocessor can access a byte of information at an odd or even memory address. But it must access a word or long word at an even memory address. So, when the microprocessor attempts to read or write a word or long word at an odd address, you see this error. Since that's a 50/50 proposition when running random code, this one shows up quite often.

So, how do we avoid these? We use a utility (I Use TechTool Pro 3 to check the RAM in the machine. If all utilities check out, then check for outdated programs. I know Quark Xpress 3.30 generated type 2 errors like nobody's business under OS 7.5.5.

If you can give more specifics as to what is happening just before the errors, that might help us narrow it down.

How much RAM have you got? I've got 705MB and I'm still looking for more. try increasing the allocated memory for QuickTime Player. Single-click on the QT Player icon (the original, not an alias) and go to the File menu at the top of the screen. Select "Get Info" and choose "Memory." I would double the recommended size. Change the Preferred Size first, then the Minimum Size. Simply close the window to save your changes. I do this with every application I install. Eliminates many memory related problems and speeds up some things. Here's what you should see:

Hehe. A bit of trouble with the UBB Code.

Hey rambo, that's cool. Wish I knew how to do that.

By the way, you only have to let us know you edited once.

Just erase the "edited..." line each time you re-edit.

Then the rest of us only see the last one.

Ya gotta applaud those bunnies for sacrificing their hearing just so some guy in Yonkers can have better TV reception.
