Apple IIe out of memory

Submitted by zulizu on July 23, 2025 - 2:10pm

Hello everyone,I'm trying to bring my Apple IIe back to life, but I'm getting an "out of memory" error, and I’m not sure where to start troubleshooting. :(

Has anyone encountered this issue before or can point me in the right direction?

Sometimes when I start the computer I'm getting this startup screen

Anyone using BMOW Yellowstone 3.5 drive controller for Apple Pascal

Submitted by old_hitech on July 22, 2025 - 12:09pm

I would like to run Apple Pascal on my Apple II+ computer with a 3.5 drive. I like the amount of storage and speed of the 3.5 drive when I run Apple Pascal on my Apple IIgs. I'd like to try it with my Apple II+. I'm not sure if the BMOW Yellowstone card supports Apple Pascal with a 3.5 drive with an Apple IIgs+. Has anyone tried this?

Hello all, 

I am writing a ASM program to run under prodos 2.4.3

The program is working well with my Virtual II emulator but when I run it on a real IIe, I have some issues.

*2000S

and then

Need help identifying cables

Submitted by gottj on July 18, 2025 - 4:15pm

I recently received a haul of some Apple hardware including lots of cables, SCSI devices, and two computers (thank you Peter!). In going through the cables, I've come across some cables that I can't identify. Please help if you are able.

 

One is a DB15 M/M cable that has pins 1 through 7, 9 through 11, and pin 13.  

The other is a DB15 M/M with pins 1 through 3, 5 through 6, 9 through 10, and pin 13.

Apex OS for Apple II?

Submitted by PraetorX on July 16, 2025 - 1:35am

Does anyone have any .dsk images with the Apex operating system for Apple?  I've searched around unsuccessfully.   I've seen a few images for something called Apex II, but that doesn't seem to be the same thing, as it runs under ProDOS and was created ~1984.

Applesauce

I have an Applesauce, but apparently it can not write a .woz file to disk. Does anyone know of a device that can?

Asking for hint: annunciators and HGR

Submitted by JulGiul on July 15, 2025 - 2:52pm

Hi everyone !

It is not the first time I read some quick phrase about Annunciators implying different behavior of HGR colors.

Are they talking about the 4 Annunciator lines in the joystick DIP socket, or something else?

 

Thank you all !

Julian
