HISTORY The Apple IIc Plus was introduced on September 16th, 1988 at the AppleFest conference in San Francisco, albeit lacking any of the excitement or enthusiasm the original Apple IIc had received when released four years earlier. Described unenthusiastically as nothing more than a "turbocharged version of the IIc with a high-capacity 3½ disk drive" by one magazine review of the time, it was an understandable disappointment. Not only did it lack any new technological advancements for 8-bit users (many current IIc users already had the equivalent features through third party add-ons) but defied common sense, as the next logical step demanded a new model of the Apple IIGS . As a result, even before the official release of the machine, it had been rumored to be a slotless version of the Apple IIGS squeezed into the portable case of the Apple IIc. Another reason for the rumor stemmed from the fact Apple employee John Arkley, one of the engineers working on the Apple IIc Plus project, devised rudimentary plans for an enhanced Apple IIGS motherboard that would fit in the IIc case, and petitioned management for the go ahead with such a project. The idea was, curiously, rejected and instead became the 8-bit computer described in this article. When the project started the original plan was to just replace the 5.25" floppy drive with a 3.5", without modifying the IIc design. Other features, consequently, were added as the project progressed. It is believed the Apple IIc Plus design, and its existence at all, was influenced by a third party Apple IIc compatible known as the Laser 128 . It is not coincidence that the Apple IIc Plus is very similar in design to the Laser 128EX/2 model, released shortly before the Apple IIc Plus. As fully backwards compatible, the Apple IIc Plus replaced the Apple IIc. Codenames for the machine while under development included: Raisin, Pizza, Adam Ant. OVERVIEW OF NEW FEATURES Three major new features Although there were several changes present, the Apple IIc Plus was mainly comprised of three new features. The first and most noticeable feature was the replacement of the 5¼" floppy drive with the new 3½" drive. Beside offering nearly six times the storage capacity (800K), the new drive had a much faster seek time (3 times faster) and button activated motorized ejection. To accommodate the increased data flow of the new drive, specialized chip circuitry called The MIG, short for "Magic Interface Glue", was designed and added to the motherboard along with a dedicated 2K Static RAM buffer (the MIG chip is the only exception to there being no new technological developments present in the machine). The second most important feature was a faster 65C02 processor, running at 4 MHz. In actuality an Apple II Accelerator product called the ''Zip Chip'' was licensed through third party developer Zip Technologies and added to the IIc Plus, however instead of the all-in-one tall chip design, Apple engineers broke out the design into its core components and integrated them into the motherboard (a 4 MHz CPU, 8K of combined static RAM cache, and logic). Of interesting note is CPU acceleration was a last minute feature added, which in turn made the specialized circuitry for the utilizations of a 3.5 drive completely unnecessary as the machine was now fast enough to handle the data flow; that circuitry was left in place and put into operation nonetheless. By default the machine ran at 4 MHz, but holding down the 'ESC' key during a cold or warm boot disabled the acceleration so it could run at a standard 1 MHz operation--necessary for older software that depended on timing, especially games. The third major change was the internalization of the powersupply into the Apple IIc Plus's case, utilizing a new miniature design from Sony (gone was the infamous "brick on a leash" external supply). A new look and minor changes Cosmetic changes were apparent as well. The keyboard layout and style now mirrored that of the Apple IIGS and Macintosh , including an enlarged "Return" key and updated modifier keys (Open and Solid Apple being replaced by "Command" and "Option"). Above the keyboard, the little used "40/80" switch was replaced by a sliding volume control (gone was the left side volume-control dial, and as a cost cutting measure, the audio headphone jack disappeared with it). The case housing and keyboard had been changed to the light-grey Apple platinum color, creating a seamless blend between keyboard and case, making them appear almost as one. The machine, a half pound lighter than the original IIc, weighed in at 7 pounds (3.2 kg). In the rear of the machine the most obvious change was a 3-prong AC plug connector and power-switch where the voltage converter had once been, an Apple security port at the far left corner, and the standardization of the serial port connectors (changed from DIN-5 to mini DIN-8, but still providing an identical signal). All the same built-in Apple II Peripheral Card equivalents and port functionality of the IIc remained, with the one exception being the floppy port. Whereas the previous IIc could only support one external 5.25 floppy drive and (in later models) "intelligent" storage devices such as the UniDisk 3.5, the Apple IIc Plus offered backwards port compatibility and more. Support for the external Apple 3.5 drive used by the Apple IIGS and Macintosh was now present, and up to two external 5.25 floppy drives could be added as well. Internally, the new motherboard sported a pin connector for an internal modem, however no products ever supported it. The same memory expansion socket introduced on late model IIc's was present, although it was not compatible with memory cards designed for the previous system. The ROM firmware (now labeled revision "5", following on the sequence from the original IIc) remained the same size, as did RAM, meaning the machine continued to ship with only 128K of memory. Negative aspects The most criticized aspect of the Apple IIc Plus, even among collectors today, is the lack of an internal 5.25 drive. The reason for this is the vast majority of software for the 8-bit Apple II series shipped on 5.25 disks (often hardcoded for the medium) making the machine of limited use unless an external 5.25 drive is added. Another unpopular change was the removal of the voltage converter. While it made the IIc Plus a more integrated one-piece unit for desktop use, the negative aspect was the loss of the ability to operate the machine from a battery source. This in turn eroded the portability aspect of the IIc series, rooting it further to a desktop-only environment. The removal of the audio-out jack used for headphones or a speaker was another feature users missed. TECHNICAL SPECIFICATIONS Microprocessor

NOTES OF INTEREST No new revisions The Apple IIc Plus had a relatively short product life span, produced for only 2 years (it was officially discontinued November 1990). During that time there were no changes or revisions made to the machine, not even to the firmware, despite the presence of bugs such as the inability to recognize single-sided 400K diskettes. No international versions There were also no international versions of the Apple IIc Plus produced, so the keyboard, unlike the original IIc, was only manufactured with English-American printed keycaps and the 'Keyboard' switch was utilized solely for changing between QWERTY and DVORAK layout (not localized language text video). Consequently, the Apple IIc Plus was only sold in the United States --not even Canadian Apple dealers were authorized to distribute or sell it. END OF THE LINE Although it wasn't intended to be, fate would have it that the Apple IIc Plus would be the last new Apple II model. Although even back in 1988, before this was known, the Apple IIc Plus could be seen as signaling the beginning of the end for the Apple II series, or at the very least a hint at the direction Apple Computer was taking with the line. In releasing the IIc Plus, Apple management essentially made a statement the Apple IIGS was no longer considered a top priority, and if anything, giving it a back seat when it was the only possible future for the evolution and continued success of the Apple II line. That in turn signified the Apple II line as a whole, despite its promise and potential, was no longer being considered important at Apple headquarters. Consequentally, from this point forward the Apple II was milked for financial gain as much as possible, yet at the same time a cap was placed on its evolution and advancement so it wouldn't overshadow and compete with the Macintosh, the company's then new focus and chosen future. Further proof of this was a year after the release of the oddly out of place and retro design Apple IIc Plus, only a minor maintenance release of the Apple IIGS was introduced (mainly boasting more RAM and improved Firmware ) rather than any of the desperately needed hardware changes required to keep the machine viable. Prototypes of more advanced Apple II's (namely in the form of a new IIGS) were delayed and eventually cancelled as the company decided what to do with its Apple II product line. The end result was to allow it to slowly fade out into obscurity due to a lack of development or support. SEE ALSO
