Hello! A friend of mine has an Apple IIc that he programs in machine code. He asked me to look around for a machine language reference guide. I don't know if this information would be in the User's Guide that was originally distributed with this machine, or if there's another source for this information. Any help would be appreciated!

Yes, the Opcodes are contained in the Reference manual, but it's very skeptical on when and where you need to use what addressing modes. Although it is an excellent reference manual.
For the Apple ][ Reference manual, scarf it from my site here:
And an unbeatable quick reference card by the Beagle Bros on 6502 OpCodes:
