Unimplemented instructions are called A-traps or F-traps, depending on the first hex digit of the instruction. Errors on Powerup I 1. For memory test failures, the first two hex digits always report the test number.

Information about products not manufactured by Apple, or independent websites not controlled or tested by Apple, is max without recommendation or endorsement. This is efficient because I only have to look up variable names mzc when writing source code and eliminates multiple lookups when debugging with Macsbug.

Apple, free use of A-traps. First, the only way to create incompatibilities is for Apple to change the locations of some or all of the global variables in a future release of system software.

Dell A Printer – Apple Community

Dell A Printer I just gave this, my old computer, to my father-in-law and cannot connect his Dell A printer Note that your submission may not appear immediately on our site. After struggling with the separated lists, I decided to improve my productivity by centralizing all that information in a master file. Since some of these locations were used for globals, the affected A-traps cannot be used more on this later.


I have added them to the resource fork of this file, so you will still be able to read them with ResEdit.

SetEntry gdBadDev [no description] generated by: If the chip is bad, the bit is set to ‘1’, otherwise the bit is zero. To do that now would be to regret my children’ – Roger Upon startup, and again if the Mac is reset, just about all variables are initialized by the ROM startup code after any memory tests see Part 6.

George Hamilton Our expert looks forward to the classical and opera highlights of This master file, MacAlmanac, has since helped me greatly.

Reply I have this question too I have this question too Me too Me too. Bit 11 determines the trap’s category: My list is in memory address order, which is better suited to debugging with MacsBug and other monitor-like debuggers.

See if Lexmark have Mac drivers for this printer. This verbal noise was particularly evident when Switcher tm later MultiFinder tm was released. To help their technicians diagnose the trouble, Apple distributed a diagram similar to the one above. Normally I use variable addresses in my source code and place variable names in comment lines.

No longer available as software updates The third-party vendor no longer provides software for the following models to download and install as software updates. The final program only has the memory addresses.

See the Apple Numerics Manual for more information. Until I can verify the accuracy of a9440 source list, treat this group of variables with extreme caution. Bits 15 through 12 are set to the binary pattern hexdecimal A for all traps. Under all newer ROMs, this location always holds a positive value. Have you downloaded the correct w940 Use this driver if you cannot print from your computer using model-specific drivers.

However, Apple excluded certain goups of traps from the retrofit process.
