All,

My Apple II Plus has this extra wire. Does anybody know why that might have been put in?

does anyone have viruses for the Apple II? I know about the ones from this link above. Does anyone have infected files or disks with these viruses? The one I managed to get is Elk Cloner. If there are viruses, then write!

cc65 users: A2SimpleIO, ProDOSi and Fields

Submitted by Harry Potter on March 17, 2025 - 6:52am

Hi!  For those here who program for the Apple2 using cc65, I have three libraries which should help to produce more efficient code.  They are A2SimpleIO and ProDOSi.  A2SimpleIO is a replacement of cc65's standard and console I/O libraries that uses the OS directly and performs little extra processing; ProDOSi is an interface to the Apple2's DOS, and Fields provides an UI that handles dialog box-like and menu support.  A2SimpleIO and Fields can be found at c65 additions - Manage /ui at SourceForge.net and ProDOSi at

Apple II ITX

Submitted by Khaibitgfx on March 16, 2025 - 2:29pm

Has anyone ever thought about relaying out the IIplus, IIe, or even possibly the IIgs mothboard in a new design to fit inside an ITX case, with possible improvements integrated into the motherboard such as the PS connector, USB keyboard and mouse?

This concept has already been done on other popular 8bit computers such as the Atari line.

cc65: Apple2enh standard binary config q?

Submitted by Harry Potter on March 16, 2025 - 10:08am

Hi!  I'm working on a special project for the C64 and 128 using cc65--even though its target is not quite cc65--and may soon want to port it to the Apple2enh and Atari targets.  This program wants both a very large main memory area and plenty of extra Low RAM via my Cubbyhole optimization technique.  A system file is not quite suitable for the task, as it leaves a 6k gap of memory unused, but my ProDOSi library could use 4k of that and leave 2k for two open files.  I really want that extra memory.  A few minutes ago, I perused cc65's Apple2enh doc and found the binary config.  How do I use

What encoding is used in of the custom alternative keyboard for the Apple2ix emulator

Submitted by EmuFans on March 15, 2025 - 11:33pm

I've been playing around with some Apple II emulators for Android lately, and one of them is Apple2ix Android. It has a really nice UI and the customizable keyboard is very flexible in terms of adjusting the UI layout for both landscape and portrait modes. I'm currently trying to figure out something about its alternate keyboard setup. It uses some json files to define the keys that the alternate keyboard displays, and one of them, 00default.kbd.json, looks like this:
