You're right, I almost forgot about that. I do remember the punch card checks I got during my early working years.
I did have a class that required the use of an 8" floppy disk. Those who haven't had the pleasure - if you ever hold an 8" floppy, you'll quickly realize they came to be called 'floppy disks'. 5 1/4" disks are downright rigid in comparison, and the 3 1/2" just kind of inherited the name because other than the media inside, it's not at all 'floppy'
The fun part was it was an 8080 assembly programming class. The need for the disk was because we had to write and compile the programs on the Cyber mainframe, and in the lab where we could then test run the programs on CP/M machines, only one was connected to the mainframe. So we had to download the program to our disk on that machine and then switch to another one to try running it. If it didn't work - back off to the computer lab (in another building!) to access the mainframe and edit/recompile. The hardware was generic 8080 S-100 bus, it wasn't a known name system like Altair or IMSAI.
Mine always worked first try - because at that time, my personal computer was my TRS-80 4P, and I had CP/M for it, so my programs were fully tested and debugged prior to keying anything in to the mainframe. A step which I still had to deal with (actually, I dialed in and text transferred it from my room, then I only had to go to the lab in the engineering building with my 8" floppy) because the requirement was to have a printed program listing and when your program worked, you had to show it running successfully to the lab TA< who then signed off on your printed copy which was what got turned in.
The year after I took the class, they filled out labs with PC compatible MS-DOS machines, I had one myself, and they used an emulator instead of the old S-100 machines. Since the process was now easier, they made the programs more difficult - I was helping someone out that next year, and their FIRST program as as complex as our LAST program. Good thing 8080/Z80 assembly was the second one I ever learned, and strongest next to my first, from my venerable old 1802 first computer.
