Merlin32 and DOS3.3 binary header

Submitted by loderunner on September 16, 2025 - 1:51pm

Hello all,

    I am trying to set up a simply development environment on my Mac to learn 6502 assembly on Apple II, it's got the following components

  • Emulator: Mariani (AppleWin Mac port)
  • Editor: VS Code
  • Assembler: Merlin32
  • Disk Image handling: CiderPress2

Basically the workflow is

1. assemble the source using Merlin32

2. using CiderPress2 to import the produced binary into disk image (.po, .do) file 

3. using CiderPress2 to set proper attributes (BINARY, AUX)

4. reboot Mariani.

Anyone have experience with using this drive? Does it work pretty well in an Apple II?

Apple II+ keycap parametric model

Submitted by profdc9 on September 14, 2025 - 10:02pm

Hello,

I have an Apple II+ that I can't get a keycap for, and I got tired of seeing it without it, so I designed a 3-D part.

It is a parametric model made in FreeCAD with adjustable dimensions so the size can be varied for the other keys.

The text for the key is embossed on the top of the key, and the key text can be changed by changing the appropriate ShapeText object.

Attaching HDD/JAZZ drive to RamfastSCI on IIGS

Submitted by Kubbie on September 13, 2025 - 5:01pm

Sorry for the noobie question but I'm trying everything poissble that I can think of o try and get my IIGS working  with the RamFast SCSI Card. My LacIE external hdd failed as the SCSI card won't reconginize it.I found an internal 50-pin SCSI drive but I'm unsure what cables to use so I can attach it as the ribbon cable connected it to the SCSI card that goes out to a 25-pin scsi header for attaching external drives in back of the IIGS.

Help identify make/model of this 80 col card

Submitted by Kubbie on September 13, 2025 - 9:03am
Can someone tell me the maker of this 80 column card? When I boot up my Apple IIE the screen is all jumbled and jumping around. I’m trying to figure out the intention of the card as which way it should face in the J0 slot. I tried changing it to different orientations since the slot is not keyed but it comes up to the Apple ][E prompt right away so I think think it’s facing in the right direction. Tia fir the help

Submitted by Kubbie on September 11, 2025 - 10:45am

I'm trying to figure out differences between these 2 revisions as I'm unable to find much info on RevB. I knoe RevC has USB port and RevB used the IDE. Can RevB mount 8 paritions at the same times so I can run "What is the Apple IIGS"?

Duodisk Calibration Woes

Submitted by Anonymoose on September 8, 2025 - 6:15pm

Recently I've been doing some maintenance on my Apples, and one of the things I've been having trouble with is tuning up the duodisk. While the Disk ][ has plenty of documentation and techincal manuals, the duo seems to be a bit sparce. I'm aware of the speed pots on the bottom, but what about head alignment/radial adjustment? Carriage limiter? Azimuth??  I do have a copy of APTEST, but I've been unsure as to what screws to turn to adjust the heads. That and the lack of detailed tech docs have left me in the dark. Any thoughts? Thanks!

Apple III ProFile

Submitted by DanielIRL on September 8, 2025 - 8:19am

Hi, I have two Apple ProFile 5MB (A9M1005) drives.

At first both passed self-test (Ready LED solid after 30s).

Using Apple /// with ProFile I/O card, I tried System Utilities + Low Level Format.

After several attempts (with two different controller boards & ROMs), now neither drive reaches Ready anymore.

Any advice on how to revive them? Could EPROM reprogramming help, or is this a controller/hardware failure?

Can this LaCie SCSI HDD be used for my Apple IIGS?

Submitted by Kubbie on September 6, 2025 - 8:54am
I found this SCSI hdd in my stash and I was wondering if this would work for my Apple IIGS with a FastRam SCSI controller? This had a label that it was used for a MAC with System 7.5.1 installed on it. Can I re-partition this hdd to work on my IIGS? I'm unable to find much info for this drive using my friend Google.
