How to set and use a IIGS prefix?

Submitted by sbaker51 on April 3, 2025 - 7:29pm

How do I set a pathname to an available IIGS prefix and how do I use that numeric prefix to access that path? I'm trying to do this within the text shell environment in ORCA. 

Can this be done within that environment, or must it be done perhaps in ProDOS 8. What is/are the commands to do so. 

Microsoft CoPilot suggests...

PREFIX #1, "/MYDIRECTORY"  to set a prefix

LOAD #1, "MYFILE"                      to access a file in that directory

AppleWin: keyboard joystick help?

Submitted by Harry Potter on April 3, 2025 - 5:42pm

I sometimes try to play Apple 2 games on the AppleWin and am confused as to how the emulated joystick works.  It seems that the Apple2 had an analog joystick.  How do I handle an Apple2 joystick on the emulator?  Same with the mouse?

Microzine issues index?

Submitted by Harry Potter on April 3, 2025 - 5:38pm

Hi!  I have open in my browser a site on asimov containing a lot of issues.  I remember when I was young playing Ask Bertha and watching people creating cards on Apple 2s at school.  I'm looking for an index of the contents of the Microzine subscriptions.  Where can I find one?

Looking for IIgs Motherboard

Submitted by rittwage on April 2, 2025 - 7:29pm

I recently rescued a IIgs from someone, but they had plugged something wrong into the disk port and completely blew the IWM chip. It is actually cracked and has a small hole in it!

I removed it, planned on just possibly using a hard drive or a disk II card in it, but it doesn't come up at all. Does the board need an IWM installed to even boot up? I get nothing on the screen at all, no beep. I do get power everywhere.

I checked the ROM and CPU are good in another IIgs, but those are the only (easily) removeable chips.

boot sector Help!

Submitted by Jiroplas on April 2, 2025 - 5:03am

I have a code that weighs exactly 1kb and I need it to end up in the boot sector of an Apple IIgs disk, which is best for a 3.5-inch Floppy disk. Can someone tell me how to put this code in the boot sector?

Announcing the 'IWMless' IWM substitution - call for beta testers

IWMless prototype

The IWMless is a small and cheap module that goes into the place of an original but dead IWM of any Apple IIc or Liron card for the Apple IIe. As the tongue-in-cheek name implies, it's  l e s s  than a real, original IWM, so it can't be used in the Mac nor in the Apple IIgs, nor in the Apple IIc+. The technical reason is that the M8 / FAST modes of the original IWM are of no use with a 6502 CPU running at 1 MHz, so they were left out of the 'IWMless' which is meant only to repair Apple IIc and Liron cards, and nothing else. The advantage of trimming these excess functions away is to get to the finish line sooner and to be able to use a low end CPLD which costs less. Or are you one of these fools who want to pay more of your hard earned money to buy features you will never use ? (Oh, the consumer product industry  l o v e s  these fools - I don't).

Apple IIGS, SCSI CD-ROM drives work once, then never again

Submitted by Fantome on March 30, 2025 - 1:46pm

Hello,

I just joined this forum and this is my first post.

As an introduction, I am not new to retro/vintage computers and have a few. Most of these were purchased new by me back in the day, including systems from Sun (SPARC 20), SGI (Octane 2, O2), NeXT TurboColor, and various Mac’s. My Apple IIGS (ROM 3) was recently excavated from storage to be brought back to life. I am a bit rusty with Apple II operations - but it’s slowly coming back.

The Frob - Reproducing it.

Submitted by Thomas Cherryhomes on March 28, 2025 - 11:47am

I know some of you are interested in making clones of The Frob (2600 gamedev system for Apple ][) based on the findings I'm getting from my research work.

I will go ahead and say that it may just be better to make a modern equivalent based on the functional description of the hardware in Chapter 2 of the Frob manual: https://archive.org/details/the-frob-a-connoisseurs-guide/page/n15/mode/2up

IIc Text Characters All Garbage - HELP

Submitted by Wavedude101 on March 27, 2025 - 8:46pm

I was trying to test a small LCD screen I wanted to make into a monitor that plugs into the monitor port of the IIc. As I was plugging in the pins, I accidentally got one of the pins wrong and plugged something into pin 15, which apparently in the Color Reference. When I turned the computer on I got the text on this image:
