Editing Apple IIc (section)

===Memory Expansion IIc (ROM version '3')===
Introduced in September 1986 simultaneously with the [[Apple IIGS|Apple II<small>GS</small>]], this model introduced a new motherboard, new keyboard, and new color scheme.<ref>{{Cite web |url=http://docs.info.apple.com/article.html?artnum=790 |title=Apple IIc (Platinum): Mouse Moved from Slot 4 to Slot 7 |access-date=February 2, 2008 |archive-url=https://web.archive.org/web/20080208145628/http://docs.info.apple.com/article.html?artnum=790 |archive-date=February 8, 2008 |url-status=dead }}</ref> The original Apple IIc has no expansion options and required third-party cards to perform various hardware tricks. This can be done by removing the CPU and MMU chips and inserting a special board into these sockets, which uses bank switching to expand memory up to 1 Megabyte ([[Random-access memory|RAM]]). This is similar to the function of the slots in the original Apple II and II+, and the auxiliary slot in the Apple IIe. The new motherboard has a 34-pin socket for plugging in memory cards directly, which allows for the addressing of up to 1&nbsp;[[megabyte]] (MB) of memory using Slinky-type memory cards. The onboard chip count was reduced from 16 memory chips (64K×1) to four (64K×4). The new firmware replaces the code for the cancelled AppleTalk networking device with support for memory cards. Bumping out the non-supported AppleTalk functionality, memory now lives in virtual slot 4, and mouse support moved to slot 7. The new keyboard no longer has the rubber anti-spill mat and offers generally more tactile and responsive keys that feel more "clicky". The color of the keyboard, floppy drive latch, and power supply cords are light grey and not "Fog", matching the new Platinum color scheme of the [[Apple IIGS|Apple II<small>GS</small>]]. The case style is still [[Snow White design language|Snow White]]. Owners of the previous IIc model were entitled to a free motherboard upgrade if they purchased one of Apple's IIc memory expansion boards; they did not receive the new keyboard or the cosmetic changes.
