More Apple ][*, //* II* and classic Macintosh hardware upgrades
Posted by jpluimers on 2025/11/14
The mini micro classic Apple emulators related post last week became way too big, so here is the classic Apple 2/Macintosh hardware upgrade part follow-up I announced in Some notes on mini/micro Apple //e emulators.
Last week, I mentioned [Wayback/Archive] ARC Javmaster – YouTube. Let’s continue from there for an even bigger post (:
Javmaster actually has a shop at [Wayback/Archive] Welcome to the 8-bit stuff store – 8 bit stuff cool retro computer 3D gadgets and geekery with a lot of interesting (mainly Apple ][ era related) retro things like:

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

Welcome to #AprilApples! Apple II Computer event celebrated in the month of April
Posted by jpluimers on 2025/04/01
Last year, #Appril][ got rebranded into #AprilApples, so I wish you a happy retro-month filled with April Apples!
[Wayback/Archive] Welcome to #AprilApples! Apple II Computer event celebrated in the month of April
Consider using the [Wayback/Archive] #AprilApples Style Guide with logon on the right, plus Garamond and/or Motter Tektura typeface when possible to really give tribute to the Apple ][ era.
Last year, a big surprise was that Apple Computer put a PDF version of the famous Apple Pascal Poster on the Internet Archive.
So today is a great day to give that more traction and link to it:
- [Archive] Apple Pascal Poster (Apple II, 1979) : Apple Computer : Free Download, Borrow, and Streaming : Internet Archive
- [Archive] OCR PDF
A year before, during April][, a remake of that poster got done on AppleFritter:

The Blast-RADIUS bomb logo reminded me of “Kaputt” in the original Castle Wolfenstein game
Posted by jpluimers on 2024/07/12
There is a Blast-RADIUS exploit that makes many uses of RADIUS vulnerable as they depend on MD5, and MD5 collisions have been sped up considerably. Basically only RADIUS TLS seems safe now.
The Blast-RADIUS logo on the right reminded me about using grenades in a game 40+ years old, so lets digress: Archive.org is such a great site, with for instance the original Apple ][ Manual of Castle Wolfenstein by MUSE Software (the manual is written in Super-Text which they also sold):
The PDF from [Archive] Instruction Manual: Castle Wolfenstein from Muse Software : Free Download, Borrow, and Streaming : Internet Archive is at
[Archive.org PDF view/Archive.is] archive.org/download/1982-castle-wolfenstein/1982-castle-wolfenstein.pdf
The trick in that game when entering a room full of SS-officers was to throw a grenade into a chest of grenades in the middle of that room, then quickly leaving the room, waiting a few seconds then re-entering that room.
Not many moves further, you would find the chest with the war plans and find the exit, then finish the game.
Back to Blast RADIUS

ApplesSoft BASIC code which includes assembly language: Twitter bot AppleIIBot could run it!
Posted by jpluimers on 2024/03/20
This was a trip down memory lane where I was totally unaware that you could embed 6502 assembly language inside AppleSoft BASIC code.
It turns you can, and even better: the Twitter bot named AppleIIBot could execute it too!
Though I bumped into AppleIIBot during winter 2021, I published the BBC equivalent last week (see BBC trip down memory lane – 8bitkick/BBCMicroBot: Runs your tweet on an 8-bit computer emulator) as that one got released earlier.
For the moment it is down because Elon blew up Twitter and shut down on 2022-11-05, but hopefully – like the BBC equivalent – it will resurface on a Mastodon instance somewhere in the future.
Luckily all old Tweets with code and rendering are still there, though you need a Twitter account to view them: Elon broke the feature of anonymous access seeing all messages in a thread.
Below the signature are the full Tweets that led me into it; the texts are these:

The Wiert Corner - irregular stream of stuff 
Depends upon which machine and ROM version you have.
The original Apple II monitor does have an S command to single step code in the Monitor. That was removed however to add other features and was not restored until ROM00 of the //c. There are however various 3rd-party ROM images that also have the Step and Trace commands, for example ROMeX and ROM4X, APPLEII.EDM, etc.
There are also hardware boards available to do this as well
