The user part of SSIO about 1984. Far right: DEC VT101 terminals. Middle: HP-2621B terminals. Extreme left: Concept APL terminal. Standing: Rob Lehman.
I think this is SSIO because that's what it says on the chairs. But now it's a Macintosh Lab. Group at center: Alan Crosswell, Rob Cartolono, ???, and Howard Eskin. I know this is 1984 because Howard wasn't here after that.
