Applesauce client v1.1 with 3.5″ disks


John Morris, the developer of Applesauce device has added support for 3.5″ drives and also released sync-sensor for the drive to be used. Applesauce client v1.1 was released in (5.5.2019) and it supported fully the Apple 3.5″ drive, reading and writing back to the disk.


It’s easiest to follow the teardown instructions by


The sync-sensor is installed next to the spinning wheel of the 3.5″ drive in bottom. The idea is the same, basicly the sensor reads the magnet strip that is installed to the spinning wheel for more accurate location of the disk.

There is room for the sync-sensor cable to route if out of the case along with the connector cable.



I had only few original 3.5″ (Apple IIGS) floppies so i chose the “Marble Madness” that i had in hand. I first read the .a2r flux image out of the disk and then made .woz out of it (analyze and save). The .woz file then can be written back to blank disk.

I booted the written copy with my IIGS (ROM3) and it worked perfectly. Pretty amazing!

“Marble Madness” (GS) – without the sync-sensor installed vs with sync-sensor installed (both booted).

John Morris about the copy protction at twitter:
“Marble Madness has an “impossible to copy” track at $20 side 1 (400+ nibbles too big) that was clocked in a way that the IIgs couldn’t write out. Applesauce detects the abnormality and re-clocks the write on the fly. This exact protection scheme proved to be so effective that many competing publishers adopted it. It evolved a bit over the years, but largely remained the same. It is structured in a way that sector copiers think they copied it, but the sectors were actually just a decoy”.

This shows how genious the Applesauce client (and John) really is!

Quick: DarkSound by ByteBoosters

The Apple IIgshave GREAT audio capabilities with it’s Ensoniq 5503 DOC – chip but there’s no connectors in the logic board for stereo output for speakers. So the DarkSound-card resolves that problem with simple, single board with connector to the logic board itself taking the signal and outputs it to external speakers/headphones or amplifier in Stereo.

The pin settings in the card you can use are as of:
*HIGH – for non-amplifed speakers (direct 8ohm, 1.5mm plug)
*LOW – for headphones or amplified speakers (1.5mm plug)
*LINE – for external aplifer / home stereo-system (3.5mm plug)

The card itself is not slot dependent, as you can install it to any slot and it will maintain the internal slot/port settings.

It also features as digizer as it have input for the signal to be digized with software.

darksoundbybyteboostersappleiigsstereocard_smallTHE PACKAGE COMES WITH:
-The board itself with adapter cable connected (to logic board)
-Stereo adapter (1.5 mm -> 3.5 mm stereo)
-Extension cable (1.5mm male to female)
-Printed installation and user instructions

Connector attached to logic board . It’s a bit tight fight with the Apple IIgs 8MBRAM/ROM-card ( but it did fit there just barely however.

Bit tight but fits.

oma_kaiuttimetI attached the card to crappy-old-Creative 2.0 speakers but they work just ok for time being.

ByteBoosters also produce other products for Apple IIGS. Available is also 4MB and 8MB RAM-expansion cards. Both are tiny and very reasonably priced.

Imaging and GS-findings

With the 5.25″ imaging done i’ve started to take a look of the 3.5″ GS disks what there might be. There seems to be some non-imaged software which would be nice to have imaged soon.

german_gs_software_smallSome German GS-software and original of “LaserForce”.

“Laser Force” loading picture.


“X-Basic” v1.0 (original) and v1.1 (copy).

Very nice crack intro (with trainer option) for “Rastan” by John Brooks.


“King of Chicago” crack screen.

voyage_au_centre_de_la_terre_disk_1“Voyage au centre de la terre” (Disk 1). Sadly the Disk 2 i missing and according by the Mr. Antoine Vignau of Brutal Deluxe fame, the Disk 2 is not been released.

And some A.U.G.E. (Apple Users Group Europe) PD disks. I’ll check if there’s any missing from the site :

Also interesting collection (10 disks+) of UniDOS formatted (800k) Apple II 8-bit games collections.

And Apple IIGS demos! There were quite nice collection of 90’s Apple IIGS demo’s. These are of cos preserved all.

Also, an original Marble Madness GS floppy. I have also the 8-bit Apple II version of it on 5.25″.

My current GS-setup (ROM3, CFFA3000, Uthernet II, 8MB RAM/ROM-card) only missing Accelerator and sound-card.. someday.


Apple IIGS in Finland

Apple IIGS was never released or sold, in Finland. Only 3 test setups were imported for testing, reviewing and for demo usage.

Tero Sand had one of these donated to and used it for programming and also for the Apple Klubi / Omenahyve magazine creation. This unit was later donated to another user but the unit is now been trashed away. Sadly.

Apple IIGS was reviewed in few magazines inc. MikroBITTI but also, Tekniikan Maailma and also PRINTTI-magazine in issue 17/1986.

Due copyright reasons, i can’t offer pdf’s out of those reviews.



Apple IIGS (ROM3) DVI-output is finally here. Me happy.

Finally using Apple IIGS (ROM3) is enjoyable! Specially in Europe, where Apple IIGS was NOT popular or like in Finland, where it was not even sold (after only importing 3 demo units).

So using your imported GS creates an challenge. Before this adapter, you had to either, get an Apple IIGS color monitor from USA and have an voltage transformer 115>230v or be lucky and find an European (230v) monitor somewhere in middle europe. No dice.
What i did before, was to have an custom Scart cable made, but that solution was far from being high quality (specially 80-colums mode was very blurry).

Koichi Nishida’s Nishida Radio to the rescue! Koichi is an electronical wizard from Japan who have created lots of products for Apple II and Japanise home computers (SORD m5).

I managed to get one finally from his webpage, where he sell’s the adapters when they are produced. You can’t just order them. He’ll announce the availability in Facebook in his page.

Where to buy?
Currently selling at 50 USD + 7 USD delivery.

Product details:

The adapter itself, works ONLY with ROM3 -units due design it uses. I believe there is work under process to create VGA/DVI/HDMI-adapters for GS ROM 0/1 versions as well but not by him.

The adapter outputs TMDS signal with either 27 MHz pixel clock (720 x 480) or 25 MHz (640 x 480) and syncs usually most LCD-monitors do sync on the signal without any issues.

The product arrived well-packaged and contained :
-The board itself
-Adapter to DVI

The adapter from the top shows the DIP-switches, DVI connector cable and additional connection for possible upgrades. The cable is slim so it can easily be slided out of the case and attached to the DVI-adapter board outside of the case, or you can mod it in the case itself.

The adapter from the bottom side. See the genius way to install it!

Installation itself was super easy. Just plug the adapter over the VGC-chip on left side, just under the Powersupply itself.

Note to myself. Don’t install Uthernet II-card in a wrong way 🙂 The GS wont boot.

Installed. it’s a tight fit but it’s, just so perfect.

It does fit under the Powersupply, just barely.

Using the ready-made GS/OS 6.0.1 from i tested the quality and it was impressive.

*More pictures will be updated *

I used temporary setup with ClassicIDE (4GB CF-card) and my 4MB RAM-card. It’s not ideal for me in many ways, so i’ve went back and put back the CFFA3000-card to it.  CFFA3000 is just perfect for any Apple II-usage in all possible ways. I need more of those..
