I was doubting it and thought it might be a similar PC, but no - there is an Amiga 4000, with CRT and keyboard. Possible another CRT in the left corner too, suggesting another machine there.
It doesn't appear to be involved in process control as it is in an office environment. I wonder what software it's used for?

As for the programme itself.. well, it takes all types, doesn't it.
