New Xdrive firmware

Submitted by jeffmazur on February 27, 2025 - 6:06pm

Xdrive firmware has been updated to V1.03 which addresses a couple of issues:

1. Images created on Windows machines would sometimes show incorrect long filename.

2. Using the N command to boot disk in lower slot did not work with CFFA.

Apple II Peripheral - Know-Drive (ABVDOS, Know-Play,etc)

Submitted by schafferm on February 23, 2025 - 11:57pm

Happy Sunday!

 

Looking for help finding documentation for the Know Drive from Abacus Enterprises in Detroit MI.    I've come across a Know-Drive and the attachment seen in the images.   I can not find any documentation or software for this - but would so much love to play with it!

 

I've found references to it, articles about it but not documentation - there has to be someone out there who has the software and/or documentation for this - any help would be greatly appreciated.

Apple IIc text is red and hard to read

Submitted by cinix on February 23, 2025 - 2:40pm

I have an Apple IIc connected to an AppleColor Composite Monitor (A2M6020). Does anyone have any thoughts on why the text describing each color is red and hard to read?

Audio/game sound effects -how were they made?

Submitted by Fuji on February 21, 2025 - 6:20pm

Ever since I got my first computer (yup, you know the one wink ) I've been fascinated and intrigued by all those cool game sound effects, despite not having a dedicated sound chip, but according to an article I recently came across ("Making the Apple II sing") it's essentially just a 1-bit square wave sound generator!

Green Monochrome A2M2010P monitor spot powerdown

Submitted by atomicham on February 21, 2025 - 2:32am

My A2M2010P is showing a bright green spot on powerdown for a couple of seconds, so it seems that the brightness circuit is still powered after power off instead of quickly closing and blocking the electrons streaming from the still hot gun.

 

I am thinking to recap it (I checked things and they seem intact, but I need to test the ESR of the caps). Any thoughts if that may fix the issue, or is there a known issue with the spot-killer circuit in this model? I don't want to burn the phosphor in the center of the screen every time it powers down.

I would like to run Doom on my Apple IIe. However, Doom floppies are upwards of $1000. Is there a legal and affordable way to play Doom?

AppleWin: screenshots?

Submitted by Harry Potter on February 16, 2025 - 7:08pm

On my Win11/64 laptop, at startup, AppleWin complains that it can't trap the PrintScreen key.  I believe it's because I have Greenshot installed on it.  I don't use it but may eventually find use for it. It doesn't do this on a Win7/64 laptop at my day program.  I tried the key there and didn't see anything.  I don't know if it did it silently or ignored the press.  I'd better check the game's folder, as it was on a flash drive.
