A while back I found copies of a CAD add on program I wrote called Ez-Shapes. Two disks, 3.5" style. One had bad blocks. I had made multiple compressed archives of both source code and object code.

Lost the object code archive for some of the project, despite having two copies.

The source code was fine, and after getting a copy of the software via (those places online), I was able to compile and run the thing as if it were 1992!

I have a USB floppy drive that seems to work well.

For grins, I plugged it into my Samsung Note 9 phone, and it WORKED! I saw 1.44Mb storage device. Hilarious!
