This little device allows you to easily transfer files from your computer to the Amiga using a simple MicroSD card. Just plug your SD2Parallel device on the parallel port of the Amiga, plug your sd card into the device, power it up, and then power up the Amiga.
You can configure it so it can automount the partition on the Workbench.

The fat95 software is required, most of the actual WB installation already has this, if not the software is available on aminet. It must be installed on L:
Copy the files SD0 and SD0.info into the devs/dosdrivers directory of your WB.
Copy the spisd.device to the devs directory of your wb.
Since the Workbench can automount all the devices that are on the devs/dosdrivers, it will not be necessary to do anything else (the mount line is available on the startup-sequence).
Note: You must set up your MicroSD card to have the first primary partition with a 2GB max size and formated in FAT32. Partitions bigger than that maybe will fail to mount).
Plug your SD2Parallel device with the Amiga power-down.
Plug your MicroSD card into the device.
Powerup the SD2Parallel device.
Powerup your Amiga computer.
The Amiga-par-to-spi adapter is based on the Niklas Ekström work, available here https://github.com/niklasekstrom/amiga-par-to-spi-adapter.
