That does look suspiciously like a Mac back there. And were'nt the Macs introduced in '84? Maybe that was a prototype. The PC looks like either a PC/AT, or an XT clone, and has a 1/2 height floppy drive. The PCs that I saw in the early 80's were still sporting full height floppy drives, and there weren't too many clone makers at the time other than Compaq, The PC/ATs were also introduced in '84, IRRC.
