From Digibarn site visitor James Henden (July 11, 2006)

I designed analog and power circuitry for AED, starting in about 1975. We originally built floppy disc systems, DEC-compatible. As that market dried up, we tried building custom, uninterruptible, DC power supplies, the video terminal (There was a Mitsubishi monitor packaged to sit on top of the pictured keyboard/chassis.), and finally, a multi-terminal small business system with multiple hard disc drives, etc. Tom Sacco was president, also a bass fisherman. Bill Kurdjewski was principal engineer. Jerry Kennedy VP Marketing. Tom Sacco appears to have retired to Florida and started a business building custom golf clubs along the way. AED was unable to tie into anything with acceptable profit margin, and max'ed out at about 200+ employees, I think. They were at 440 Potrero, and the small trees that grew on the street are now towering giants. Quite a few young assemblers, technicians, PCB layout guys, and engineers started out there. Another guy that worked on video stuff was Hildon Gold.
