Were the Apple IIc and the Gradiente Expert made by different companies?
Apple IIc 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.
Macintosh IIx The Macintosh IIx was introduced by Apple Computer in 1988 as an incremental update of the original Macintosh II model. It replaced the 16 MHz Motorola 68020 CPU and 68881 FPU of the II with a 68030 CPU and 68882 FPU running at the same clock speed; and the 800 KB floppy drive with the 1.44 MB SuperDrive (the first Mac to have this feature). The initial price of the IIx was US$ or US$ for a version with the 40 MB hard drive.
