When we create the copy of the ROM chip memory using the TL866II+ programmer it is called 'ripping'.īegin by downloading the appropriate Windows software for your TL866II+.

You can consider the process like a photocopy. When the term 'image' is used you can metaphorically imagine a 'snapshot' of the entire ROM chip memory. I also host ROMs which I pulled from my own chips in GitHub, which you can find linked in the next section. If you don't have working ROM chips or would prefer to download a copy, you can find many popular ROMs listed on the ' Macintosh Repository' website - a great resource for the community ( Direct Download link). You will need an image of an existing working ROM in order to produce new replacement chips. Ripping ROM is the process of reading all of the ROM chip memory to your computer. The memory in the ROM chips is programmed to issue important instructions like loading the operating system from the hard drive and much, much more. On the technical side, ROM is 'Read Only Memory' - two physical computer chips installed on your Macintosh Plus logic board which issue commands to the CPU. If the metal pins are damage your ROM chip may become an interesting piece of trash. It should be noted that this guide will not cover how to physically uninstall or install your ROM chips but please understand removal and installation of ROM chips should be a delicate process. However, it is possible on Linux and Mac OS with more effort. For simplicity sake I will describe the process of ripping ROM images on Windows, as it is the most straight forward process with the TL866II+. Let's talk about 'ripping' ROM images from physical chips.
