DuoDisk drive 2 unresponsive

Submitted by okto on May 6, 2026 - 7:44pm

I have a DuoDisk where drive 1 works perfectly, but drive 2 does not respond. No motor movement, activity LED doesn't even light. If I plug the second drive mechanism into the analog board as if it were drive 1, it works perfectly, so it seems like xomething in the drive-selection logic on the analog board isn't working right.  

Is there a likely culprit for this behavior, and how should I start diagnosing?

Submitted by YLG80 on May 1, 2026 - 7:30am

Here are two 8-INCH disk interface cards developed in the apst for the ITT-2020.

As far as we can read on the EPROM on the final release card, it was developed by NovoComp Datensystems GmBh in Germany.

I have only found the former address of that company:

Novocomp Datensystems GmH,  Walramsneustr 9 ,D - 54290 Trier ,Germany

 

Here is the released

SSM parallel card info?

Submitted by bobclark86 on April 28, 2026 - 3:34pm

I picked up an Apple IIe (early 1984 by the board and chip dates), and it included this card along with a much later 80-column and an age-appropriate Disk II controller. The card came with a 26-pin cable plugged into it with a Centronics connector on the end, so I'm sure it's a parallel printer card. I found a copy of a ROM dump on apple2.org, but no documentation.

A2Pico2Lite

Submitted by ol.sc on April 28, 2026 - 10:34am

A2Pico has become a product family :-)

The original A2Pico card has a microSD card slot. But most A2Pico firmwares don't make any use of an SD card. By eliminating the microSD card slot and using a second-generation Raspberry Pi Pico chip, the complexity of the original A2Pico card was significantly reduced.

The result is the new A2Pico2Lite card. At $20, it's even cheaper than the already very affordable A2Pico at $30 (which will continue to be available):

A remix of PTB (Dave)'s amazing Floppy EMU case

Submitted by Stargeezer on April 26, 2026 - 10:26pm

Howdy friends:

A few years ago fellow Fritter Friend Dave, aka @PTB created an amazing Floppy EMU case from an original Apple Floppy II case.  At the time I did nto have the funds available for a kit.  Recently I learned Dave no longer had kits but shared all the various files he used to create the case (see link above).
