Art of the IIe project grew out of the earlier work on custom integrated circuits for the Apple II. When they finally decided to go ahead and improve the design by adding new features, one of the original plans was to give the Apple II an 80-column text display and a full upper/lowercase keyboard. Walt Broedner at Apple did much of the original hardware planning, and was one of those at Apple who pushed for the upgrade in the first place. To help maintain compatibility with older 40-column software (which often addressed the screen directly for speed), he decided to make 80-columns work by mirroring the older 40 column text screen onto a 1K memory space parallel to it, with the even columns in main memory and the odd columns in this new “auxiliary” memory. To display 80-column text would require switching between the two memory banks. Broedner realized that with little extra effort he could do the same for the entire 64K memory space and get 128K of bank-switchable memory. They put this extra memory (the 1K “80-column card”, or a 64K “extended 80-column card”) in a special slot called the “auxiliary” slot that replaced slot 0 (the 16K Language Card was going to be a built-in feature). The 80-column firmware routines were mapped to slot 3, since that was a location commonly used by people who bought 80-column cards for their Apple II computers, and was also the place where the Apple Pascal system expected to find an external terminal. The auxiliary slot also supplied some special video signals, and was used during manufacture for testing on the motherboard. The engineers who worked on the IIe tried hard to make sure that cards designed for the II and II Plus would work properly in the new computer. They even had to “tune” the timing on the IIe to be slightly off (to act more like the II Plus) because the Microsoft Z-80 Softcard refused to function properly with the new hardware. A socket was included on the motherboard for attaching a numeric keypad, a feature that many business users had been adding (with difficulty) to the II Plus for years. The full keyboard they designed was very similar to the one found on the Apple III, including two unique keys that had first appeared with the III–one with a picture of an hollow apple (“open-apple”) and the other with the same apple picture filled in (“solid-apple”). These keys were electrically connected to buttons 0 and 1 on the Apple paddles or joystick. They were available to software designers as modifier keys when pressed with another key; for example, open-apple-H could be programmed to call up a “help” screen. The newer electronics of the keyboard also made it easier to manufacture foreign language versions of the Apple IIe Over all, Broedner and Peter Quinn (the design manager for the IIe and later the IIc projects) and their team managed to decrease the number of components on the motherboard from over one hundred to thirty-one, while adding to the capabilities of the computer by the equivalent of another hundred components.

IIe项目的技术发展源于早期在苹果II上定制集成电路的工作。当他们最终决定继续推进并通过添加新功能来改进设计时,一个最初的计划是为苹果II配备80列的文本显示和全大小写键盘。苹果的沃尔特·布鲁恩德纳(Walt Broedner)负责了许多原始硬件的规划,是苹果中推动升级的主要人物之一。为了与较旧的40列软件(通常直接操作屏幕以提升速度)保持兼容,他决定通过将旧的40列文本屏幕镜像到一块平行的1K内存空间中,从而实现80列显示,奇数列存放在这块“辅助”内存中,偶数列存放在主内存中。显示80列文本就需要在两块内存之间切换。布鲁恩德纳意识到,花费不多的额外努力,就可以实现整个64K内存空间的同样功能,从而获得128K的可切换内存空间。他们将这额外的内存(“80列卡”1K,或者“扩展80列卡”64K)放在一个被称为“辅助”插槽的特殊插槽中,该插槽取代了插槽0(原计划的16K语言卡将作为内置功能)。80列固件例程被映射到第3插槽,因为那是一个

这是苹果二代电脑的80列卡片购买者常用的位置,也是苹果 Pascal 系统期望找到外部终端的地方。辅助插槽还提供一些特殊的视频信号,在制造过程中用于主板的测试。

为确保为II和II Plus设计的卡在新电脑中正常工作,工程师们付出了巨大努力,试图调整IIe的时序,稍微偏离,以更像II Plus的表现,因为微软的Z-80 Softcard在新硬件上无法正常运行。主板上还配备了一个插槽,用于连接数字键盘,这是许多商务用户多年来在II Plus上难以添加的功能。他们设计的全键盘与Apple III上的键盘非常相似,包括两个在III中首次出现的独特按键——一个带有空心苹果图案(“开-苹果”),另一个则是填充的苹果图案(“实心-苹果”)。这些按键在电气上与Apple的操纵杆或摇杆上的按钮0和1相连接。当与其他键同时按下时,作为修改键供软件设计者使用;例如,可以编程为“开-苹果-H”呼出“帮助”屏幕。键盘的新版电子元件也使得制造外语版本的Apple IIe变得更加容易。

总的来说,Broedner 和彼得·奎因(IIe 以及后续的 IIc 项目的设计经理)及其团队成功地将主板上的组件数量从一百多个减少到三十一,同时通过增加相当于另外一百个组件的功能,提升了计算机的能力。
