The 65C02 added more CPU instructions, the new character ROM added 32 special "MouseText" characters (which allowed the creation of a GUI-like display in text mode, similar to IBM code page 437), and the new ROM firmware fixed problems and speed issues with 80-column text, introduced the ability to use lowercase in Applesoft BASIC and Monitor, and contained some other smaller improvements (and fixes) in the latter two (including the return of the Mini-Assembler—which had vanished with the introduction of the II Plus firmware). To support this, special double capacity video and keyboard ROMs are used; in early motherboards they had to reside on a tiny circuit card that plugged into the socket. During its lifetime, 100,000 units are produced. Slinky RAM cards). Despite the hardware changes, the IIe maintains a high degree of backwards compatibility with the previous models, allowing most hardware and software from those systems to be used. 1983: January - Apple Computer introduces the Apple IIe for US$1400. As video is emulated using Macintosh QuickDraw routines, it is sometimes unable to keep up with the speed of a real Apple IIe, especially in the case of slower host machines. Sometimes the differences were very minor, such as extra local language characters and symbols printed on certain keycaps (e.g. There were no firmware changes present, and functionally the motherboard was otherwise identical to the Enhanced IIe. Free shipping for many products! Apple Computer planned to discontinue the Apple II series after the introduction of the Apple III in 1980; the company intended to clearly establish market segmentation by designing the Apple III to appeal to the business market, leaving the Apple II for home and education users. Internally, a (reduced in size) Extended 80-Columns Card was factory pre-installed, making it come standard with 128 KB RAM and Double-Hi-Res graphics enabled. Describing the last as a software-compatible Apple II replacement—"A 6502 machine using custom LSI" and a simpler motherboard—it said that Diana "was ready for release months ago" but decided to improve the design to better compete with the Xerox 820. This final model of the Apple IIe (not sold in Europe) was quietly discontinued on November 15, 1993, which (following the discontinuation of the Apple IIGS a year earlier) effectively marked the end of the Apple II family line. The original IIe uses a case very similar to the Apple II Plus, painted and with Velcro-type clips to secure the lid with a strip of metal mesh along the edge to eliminate radio frequency interference. After 3 1⁄2 years of the Apple II Plus, essentially at a standstill, came the introduction of a new Apple II model — the Apple IIe (codenamed "Diana" and "Super II"). This change resulted in reducing the cost and size of the motherboard. The purpose of the update was to make the Apple IIe more compatible with the Apple IIc (released the previous year) and, to a smaller degree, the Apple II Plus.

It can run at either standard 1 MHz speed or an accelerated 1.9 MHz. In order to support this, some modifications had to be made to the motherboard, which became the Revision B. During approximately the same time period the Platinum IIe was being produced (1987), Apple released an alternative machine for the European market. Byte magazine referred to the Apple II, Commodore PET 2001 and the TRS-80 as the "1977 Trinity." It is completely identical to the previous machine except for 4 chips changed on the motherboard (and a small "Enhanced" or "65C02" sticker placed over the keyboard power indicator). Apple provided technical information on the IIe to hundreds of developers before its release, and claimed that, as a result, 85 to 90% of Apple II software worked with it. In January 1987 came the final revision of the Apple IIe, often referred to as the Platinum IIe, due to the color change of its case to the light-grey color scheme that Apple dubbed "Platinum". Although it affected compatibility with a small number of software titles (particularly those that did not follow Apple programming guidelines and rules, used illegal opcodes that were no longer available in the new CPU, or used the alternate 80-column character set that MouseText now occupied) a fair bit of newer software — mostly productivity applications and utilities — required the Enhanced chipset to run at all. This change involved a new processor, the CMOS-based 65C02 CPU, a new character ROM for the text modes, and two new ROM firmware chips.
