Crikey! No 3D, no shape layers, no text layers, and if I'm not mistaken, no RAM preview!
We've come a long way.
Actually, After Effects version 4.0 introduced RAM preview. It came out in January 1999. Version 4.1 which came out in September of 1999 introduced flowchart view, watch folder, 3D channel effects, collect files command, watch folders, auto deinterlacing, sequence layers, save favorite effects (.ffx), separate text fill/stroke, and 30,000×30,000 image support
