I almost completed CS50 last year, and I was just wondering if I could finish up the coursework with the old appliance, or do I need to install the new one? Thank you!
You should be able to complete pset7 and the new pset6 and pset8 using the old appliance. There's also a new program
initials.c in pset2 so you'll need to do that (and you won't have
check50 for it with the old appliance if you're okay with that.)
If your system supports it, I'd suggest getting the new appliance only because that way you'll have the most up to date working space, but I think you'll be okay if you don't.
