DB192IDC20

A adapter for connecting a Apple UniDisk to an Apple Drive II card

A small adpater to connect an Apple UniDisk with an DB19 connector to a Apple Drive II interface card. I only using this for an Apple II+, so there is no switching or any kind of drive detection circuits, just a straight pin to pin connection.

Parts.

  1. 3D printed shell (Resin Print)
  2. DB25F (for harvesting the pins)
  3. IDC20 connector
  4. PCB

Note. the shell is resin printed with Siraya Tech Blu.

Questions

How big is the DISK2BREAKOUT PCB?

It measures 36.8 × 41.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the DISK2BREAKOUT use?

6 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the DISK2BREAKOUT KiCad files?

From the terenceang/DB192IDC20 repository on GitHub, at the commit this page was made from: the board is PCB/DISK2BREAKOUT/DISK2BREAKOUT.kicad_pcb and its schematic PCB/DB192IDC20/DB192IDC20.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the DISK2BREAKOUT design in my own project?

Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
