A while ago I bumped into this video about likely the rarest model in the Apple II series: the Apple IIc Plus:
[Wayback/Archive] Apple IIc Plus – the rarest and fastest Apple II! – YouTube
Returning to one of my favorite subjects – the Apple II – I decide to finally repair a broken Apple IIc Plus gifted to me a little more than a year ago. This machine was the final true hardware revision to the Apple II line, coming in 1988, and the last standalone machine in the line released. It was also the fastest, with a 4Mhz CPU (vs. 1Mhz in most other Apple II’s, and 2.6Mhz in the IIGS). But it was a problematic machine for Apple, with a concept that had been watered down to the point of, well, pointlessness.
The market wanted it even less than it wanted the original IIc (which was my first computer – the one in the thumbnail is my original machine). Still, it is an interesting computer for its accelerated CPU, and its somewhat anachronistic nature at the time of its launch.
It has a cool demo of Flight Simulator II demo mode (which back in those days crashing the plane – demo modes luckily improved from there :) at both 1 Mhz and 4 Mhz. It indeed is not smooth, but a lot faster.
The problem back in those days with acceleration is it would not just improve render speed, but also increase clock time speed. It made most games almost impossible to play in accelerated mode.
If I ever get one, I need to replace the 110V power supply with a 240V/110V auto-switching one as per [Wayback/Archive] IIc + 240v Power:
