Amiga 3000 new owner

Welcome to the world of Amiga 

If the machine is booting to the kickstart screen thats a positive. Get a copy of Workbench on floppy WB3.1 is easily available. Also get a copy of Amiga Test Kit (on git hub here https://github.com/keirf/Amiga-Stuff/releases); VAT (Versatile Amiga Test Progam) is also worth getting hold of (Aminet) https://www.aminet.net/package/util/misc/VATestprogram. You can use both to test the machine for hardware faults.

If the 3000 is your only amiga writing to floppy is going to be a challenge.

One option would be to use a Gotek drive either internal or external. I had this challenge with an A2000. My solution was to get a gotek and install it replacing DF0: (main floppy drive). https://www.amigakit.com/amiga-gotek-floppy-drive-emulator-grey-p-1284.html?aksid=aemcuud9uoelsli3islsvsj474&currency=GBP&aksid=aemcuud9uoelsli3islsvsj474 I could then download the .adf's and write them to a USB stick and used that to boot into WB3.1.

Good luck.
