    Another IIci ROM hack

    You can decode the address range 0xFAXXXXXX with 2 chips if you have a 7400 (quad 2-input NAND) and a 7432 (quad 2-input OR). This leaves one extra NAND gate.

    TomeViewer workaround for Mac OS ROM file (sheepshaver)

    Obtaining the Mac OS ROM file requires an old Mac to run TomeViewer and extract it from the Mac OS ROM update installer. This is not readily available to everyone who would like to use Sheepshaver. Would it technically be legal to provide a patch that once applied to the compressed Mac OS ROM...

    Binary recompilation from 68k to OS X - why not?

    If this was simple, someone would have done it. This proves to me that there is a lot that I am not aware of concerning what all goes on between 68k apps and Mac OS Classic. I am wondering why, instead of a complete system emulator approach that boots Mac OS - a computer in a window, what...

    Hidden ROM/extension images

    This is a test to see if it is possible to attach binary files in this forum by means of JPEG. To see if it works, download the attached image and expand it with: unrar x archive.jpg Or possibly rename it to archive.rar and double-click it.

    Hidden ROM/extension images

    This picture came from a 7.6.1 installation but appears to have come from an erased file on the hard drive. When I mount sheepshaver's hard drive image and create a new disk image from it with Disk Utility, this picture is not included in the new disk image. I think that the installer may have...

    Hidden ROM/extension images

    These are from somewhere in the NetBoot Mac OS 9.2.2 disk image. I'm not sure which file they came from. The Apple campus image is also somewhere in this disk image, but not the iguana flag. I realize this is a bit off-topic, but these discoveries have indeed stemmed from the PEX ROM. If a...

    Hidden ROM/extension images

    I found a better jpeg extractor and fed it my entire Mac ROM archive. Much to my surprise, here are the Quadra 660AV / 840AV hidden jpeg images :)

    Hidden ROM/extension images

    MOTHERLOAD of JPEG easter eggs found in the 7200 / 7500 / 8500 / 9500 ROM! These are stored amongst the "secret about box" images. See the next post for those. (Max # of attachments is 5.)

    Hidden ROM/extension images

    OMG, there's one in the Power Mac G3 ROM too! :D Who knows how to access these normally?? This one is located at 0x2E6E80:2FC268 in the checksum = 0x78F57389 ROM.

    PEx ROM Project

    I figured it out! I didn't know where to find the end of the image data before, but after a little googling, I realized that they end with 0xFFD9. There happens to be an extra 0xFFD9 in the image data before the end and I think that could be what caught up the JPEG extraction program.

    PEx ROM Project

    I found a JPEG header at address 0x2D14E0 by searching for "JFIF". I don't know much about JPEG so I used a program that finds and extracts JPEG images. The bottom half of the image is missing, maybe someone can tweak it and get the rest.

    Mac OS 9.2.2 on older Power Macs and sheepshaver

    Did anyone ever find a hack that would get 9.2.2 to work on older Power Macs and thus sheepshaver? This would be quite useful for use with sheepshaver considering the NetBoot9 disk image freely available from Apple that contains a 9.2.2 system folder. http://support.apple.com/kb/DL1192 I...

    Character palette glitch leads to possible prank opportunity

    I must have changed resolutions or something because my character palette's title bar was squarely under the menu bar in 10.4.11, so I couldn't move it. There's no keystroke to zoom the character palette because of its floating nature and only the title bar is draggable. After a brief period...
