The Macintosh IIcx is a personal computer designed, manufactured and sold by Apple Computer, Inc. from March 1989 to March 1991.
 Introduced half a year after the Macintosh IIx, the IIcx resembled the IIx to a great extent and provided the same performance, but was quieter (due to its quieter fan on a smaller power supply) than its predecessor.
 Reducing the number of NuBus slots from 6 to 3 also made the machine much more compact.
 The new case, Apple's first to be designed to operate in either a horizontal or vertical orientation, remained in use for its successors the IIci and Quadra 700.
 The idea for vertical orientation, one of the first minitower cases, was suggested by Apple CEO John Sculley, who was running out of space on his desk, despite the fact that the new layout actually took more space once the monitor was taken into account.
 The model was designated IIcx for "compact" (echoing the earlier Apple IIc compact model in the Apple II series), and the "x" was Apple's designation for the 68030 processor.
MouseText designed by Bruce Tognazzini is a set of 32 graphical characters first implemented in the Apple IIc.
 They were then retrofitted to the Apple IIe forming part of the Enhanced IIe upgrade.
 A slightly revised version was then released with the Apple IIgs.
Dazzle Draw is a bitmap paint program for the Apple IIc and Apple Enhanced IIe home computers.
 The program allows users to create bitmap images such as drawings, cartoons, charts, and so forth, which can then be printed or used in other programs.
The Echo II was a plug-in expansion card, speech synthesizer card for the Apple II and Apple IIc personal computers that allowed applications to use speech synthesis.
 The Echo II used the TMS5220 speech synthesis chip to synthesize speech.
 The Echo II software could synthesize either unlimited text-to-speech using stitched phonemes, or play back raw LPC data for specific words, with resulting higher speech quality.
The Apple IIc, the fourth model in the Apple II series of personal computers, is Apple Computer’s first endeavor to produce a portable computer.
 The result was a 7.5 lb notebook-sized version of the Apple II that could be transported from place to place.
 The "c" in the name stood for "compact", referring to the fact it was essentially a complete Apple II computer setup (minus display and power supply) squeezed into a small notebook-sized housing.
 While sporting a built-in floppy drive and new rear peripheral expansion ports integrated onto the main logic board, it lacks the internal expansion slots and direct motherboard access of earlier Apple IIs, making it a closed system like the Macintosh.
 However, that was the intended direction for this model — a more appliance-like machine, ready to use out of the box, requiring no technical know-how or experience to hook up and therefore attractive to first-time users.
The Apple IIc Plus is the sixth and final model in the Apple II series of personal computers, produced by Apple Computer.
 The ""Plus"" in the name was a reference to the additional features it offered over the original portable Apple IIc, such as greater storage capacity (a built-in 3.5-inch floppy drive replacing the classic 5.25-inch drive), increased processing speed, and a general standardization of the system components.
 In a notable change of direction, the Apple IIc Plus, for the most part, did not introduce new technology or any further evolutionary contributions to the Apple II series, instead merely integrating existing peripherals into the original Apple IIc design.
 The development of the 8-bit machine was criticized by quarters more interested in the significantly more advanced 16-bit Apple II.
Open architecture is a type of computer architecture or software architecture that is designed to make adding, upgrading and swapping components easy.
 For example, the IBM PC and Apple IIe have an open architecture supporting plug-in cards, whereas the Apple IIc and Amiga 500 computers have a closed architecture.
 Open architecture systems may use a standardized system bus such as S-100, PCI or ISA or they may incorporate a proprietary bus standard such as that used on the Apple II, with up to a dozen slots that allow multiple hardware manufacturers to produce add-ons, and for the user to freely install them.
 By contrast, closed architectures, if they are expandable at all, have one or two "expansion ports" using a proprietary connector design that may require a license fee from the manufacturer, or enhancements may only be installable by technicians with specialized tools or training.
Impossible Mission II is a 1988 computer game developed by Novotrade and published by Epyx.
 It was released for the Commodore 64, ZX Spectrum, Amstrad CPC, Enterprise 64 and 128, Nintendo Entertainment System, MS-DOS based PCs, Atari ST, Apple IIe with at least 128K, Apple IIc, Apple IIGS and Amiga computers.
 In 2004, it was one of the games featured on the C64 Direct-to-TV.
Star Trek: The Kobayashi Alternative was a "Star Trek" themed computer software game, designed for the Apple II Plus, Apple IIe, and Apple IIc.
 The game was also available for the Commodore 64, Macintosh and IBM PC.
 This text adventure was first published in 1985 by Simon & Schuster.
 The player assumes the role of Captain James T. Kirk.
 As Kirk, the player commands the actions of the "Enterprise" crew, as well as the "Enterprise" itself.
 The game was expansive and ambitious, but also very buggy .
The Expert, made by Gradiente Eletrônica (to date best known as a game console and Hi-Fi equipment company) was the second and last MSX home computer launched in the Brazilian market, in the mid-1980s.

Question: Were the Apple IIc and the Gradiente Expert made by different companies?
Answer: yes
