I just picked up an Atari Portfolio off of Facebook Marketplace in my area and ordered a new-old-stock parallel interface adapter. I'm still working out how to get it interfaced to my PC through an Arduino to copy up files. It's a very charming device. I used to own one in the mid-to-late 90s as well that I got used from the local computer store in my small town.
