The loopback test is how you verify the SCC! There is a program called "Snooper" for the Mac. It's a diagnostic program that I use to use with EMPLANT (the Mac emulation board I made for the Amiga). My board had real SCC ports and the loopback test would pass on it using Snooper. You could try to find that program (I am sure that Archive.org or some other place has it), and try that with your Mac. I am not sure what the Mac Classic II uses for the SCC. If it's the standard DIP package 85C30 then I happen to have hundreds of those chips still if you can't find one.
