Designed to enhance the system, it provides improved performance, including faster turbo clock speeds (up to 3.2X) and better video signal stability compared to the original 1986\/1987 chips. The MMU (Memory Management Unit) increases the original 512 kB memory limits to 2 MB.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurpose:\u003c\/strong\u003e It acts as a modern, reliable, and faster replacement for the stock GIME chip, which is responsible for memory management, graphics, and interrupts in the CoCo3.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerformance:\u003c\/strong\u003e It enables faster clock modes, specifically \u003ccode\u003ePOKE 65497,0\u003c\/code\u003e for 2X (FAST) and \u003ccode\u003ePOKE 65497,\u0026amp;H5A\u003c\/code\u003e for 3.2X (TURBO).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVideo Improvement:\u003c\/strong\u003e It resolves issues found in original 1986 GIME chips regarding HSYNC pulses and RGB output, allowing for better compatibility with modern display converters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e It is installed directly onto the motherboard's PLCC socket, often requiring careful handling of the underlying hardware.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eInstalling a GIME-Z\u003c\/strong\u003e\u003cbr\u003e\n\u003ca href=\"https:\/\/www.youtube.com\/watch?v=zxkgcXt59kU\" target=\"_blank\"\u003ehttps:\/\/www.youtube.com\/watch?v=zxkgcXt59kU\u003c\/a\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBuilding an All-New CoCo 3!\u003c\/strong\u003e\u003cbr\u003e\n\u003ca href=\"https:\/\/www.youtube.com\/watch?v=fB1BmakU_pg\" target=\"_blank\"\u003ehttps:\/\/www.youtube.com\/watch?v=fB1BmakU_pg\u003c\/a\u003e\u003c\/p\u003e","brand":"CoCo Bits","offers":[{"title":"Default Title","offer_id":52277661434135,"sku":null,"price":115.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/0757\/8903\/files\/GIMEZ_orthog.jpg?v=1771385410","url":"https:\/\/cocobits.org\/products\/gime-z-upgrade-for-the-color-computer-3","provider":"CoCo Bits","version":"1.0","type":"link"}
