Hi. I was wondering if you anyone could help me with Computer Architecture. I am having a hard time trying to get access to the two systems with different processor architectures, which are x86 and POWER8 using Terminal on my MacBook.

For x86, I have to use zeus.cs.txstate.edu. For POWER8, I have to use capi.cs.txstate.edu.

When I try to access them in the Terminal, it keeps saying "command not found" or gives me a blank line. I might insert the terminal code incorrectly, but I don't know what is the correct way to get access to the two systems.

Thanks.
