The first DTK is housed in a modified Power Mac G5 case. Intel Developer Transition Kit Logic Board. During Apple's 2005–2006 transition from PowerPC to Intel processors, the company made available the first Developer Transition Kit (DTK), a prototype Intel-based Mac computer for developers.
Battery: A 3.6 V 1/2AA lithium battery, which must be present in order for basic settings to persist between power cycles, is located on the logic board. Macintosh SE machines which have sat for a long time have experienced battery corrosion and leakage, resulting in a damaged case and logic board. Some SE models feature a board-mounted battery ...
At the time of its introduction, Apple promised an inexpensive logic board upgrade to the 7500, but due to high demand for the 7500, this never materialized. When the upgrade was finally made available, it was to the follow-on model, the Power Macintosh 7600 , and came in the form of a complete logic board replacement. [ 3 ]
An analog board is a circuit board that contains the majority of analog circuitry in certain Apple Macintosh computers. The analog board was one of two circuit boards within many early Macintosh computers, including the Macintosh 128K/512K/Plus, Macintosh SE series, and Macintosh Classic series. The analog board contained several capacitors, a ...
It is also the only MacBook Pro to support nine versions of macOS, from Mac OS X Lion 10.7 through macOS Catalina 10.15. Early and late 2011 models with a GPU; 15" & 17"; reportedly suffer from manufacturing problems leading to overheating, graphical problems, and eventually complete GPU and logic board failure.
There were problems with batteries on some 2007 models not being read by the MacBook. This is caused by a logic board fault and not a fault with the battery. [citation needed] In February 2010, Apple announced a recall for MacBooks bought between 2006 and 2007 for hard drive issues. This is caused by heat and other problems. [citation needed]

Video: The LC II's logic board has one video RAM slot, which is filled with a 256 KB SIMM as standard; the high-end configuration was shipped with a 512 KB SIMM instead. VRAM SIMMs from the original LC are supported in the LC II. [5] Upgrades: Apple sold a $599 upgrade kit that replaced the LC II's logic board with that of the LC III. [4]
