From the project
KiCad project and Gerber files for an adapter that converts the Atari ST external 14 pin floppy connector to a standard 34 pin IDC box header.
This repository contains the KiCad project and Gerber files for an adapter that converts the Atari ST external 14 pin floppy connector to a standard 34 pin IDC box header. The 14 pin floppy connectors are out of production for a long time and are extremely hard to get hold of and expensive nowadays. This adapter is a cheap workaround.
This floppy adapter is designed to be used in combination with my DSUB-19 Adapter for the Atari DMA/Harddisk port, they fit nicely next to each other. I also tried not to block other connectors, but I only have an Atari 1040 STF to check that, so your mileage…
