And I'm happy with that because it does not fit into the cabinet any more... But since these drives are from a later date then this PDP11 I thought lets keep de video simple with the devices from that time.
Hi Roland, I’m not sure what the model of the floppy drive was, just that it was a seperate dual single sided 8 inch drive unit in the same room as the user terminals while the main unit rack was in the adjacent room. This was 1978 onwards if that helps identify the possible model.

There was another machine in the system room with a vector graphic display. It might have been a PDP10. We would sometimes get to play moon lander on it, the objective was to land close to McDonalds.
