An interesting observation is that quite a number of Sun-3 workstations can be seen in these pictures. NeXTstep was originally developed on 68k-based Sun machines, version 0.6 was running on Sun hardware according to blackholeinc's Rob Blessin. The first NeXTstep version for 68k NeXT hardware still supported executing SunOS a.out binaries in addition to Mach-O ones.
I know this era is gone - neo modern box building on a sprawling campus building a changing technology that hte world doesnt yet know it needs. Todays developers and engineeers rebel like they are being caged like an animal to be in such an evironment.
