There are definitely Amiga 2000s in the photos but most of the monitors have PC-style keyboards in front of them (look above the cursor keys - the Amiga one only has 2 keys (Del and Help) there rather than 6 and only 8 function keys, not 12). It's possible they're attached to Amiga 2000s with adapters but between that and what's on the monitors, I'm pretty sure most desks are primarily running DOS PCs.
