Some links on the Apple IIc Plus (Apple IIc + on the boot screen) likely the rarest from the Apple II series

Posted by jpluimers on 2025/05/16

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 perΒ [Wayback/Archive] IIc + 240v Power:

The video is on the walled garden called Instagram as well, but since I intentionally don’t have an account there accessing is hard. Anyway, it is at:Β [WaybackSave/Archive] Instagram: β€žCyber Gangsta’s Paradiseβ€œ feiert Premiere 🎢🎬.

In the past, picuki was an alternative. Now it fails for instagram content.Β  [Wayback/Archive] Instagram Reels Download with Reels Downloader got me toΒ [Wayback/Archive] cdninstagram, which in the end worked.

Yes, you can globally block JavaScript and enablpe per-site, but you block Bookmarklets too

Posted by jpluimers on 2025/05/16

Trying to trim down excessive CPU usage of my web browsers, and lessen the risk of intrusion, I experimented with globally disabling JavaScript and only enabling it on sites where it adds value to me.

That is possible (see below), but immediately showed a big side effect: Bookmarklets will not work on sites that have JavaScript disabled.

Disabling JavaScript globally only allows Bookmarklets on sites where you have enabled JavaScript. Not the situation I hoped for (:

I’ll try it for a while though.

I wonder how long this can be hosted on GitHub. Will start using it, just to learn more about the GitHub computing infrastructure.

Early Firefox history thread by @asadotzler on Thread Reader App (from before it was called Phoenix, heck from before Phoenix was created!)

Posted by jpluimers on 2025/05/14

A few years back I bumped in this cool [Wayback/Archive] Thread by @asadotzler on Thread Reader App on early Firefox history (from before it was called Phoenix or Firebird, heck from before Phoenix was created!).

It is important to keep telling these bits of history as they are fundamental to understand the Web Browser landscape as it is now.

Great material that complements Wikipedia articles like these:
