Honeywell made a large number of these systems, which were in use in
many industries (oil refining, manufacturing of all types, water utility
distribution, etc.). They were quite expensive, and PLC manufacturers
have made great inroads into that market in the past couple of decades.
As a result, some of that equipment is showing up in the surplus market.
I found a Honeywell "Orion" console desk being disposed of that I would
have loved to take, except that it was truly massive (it must have
weighed nearly a thousand pounds!). It was electrically height
adjustable (with memory), had mounts for two very large monitors,
integrated lighting, cable management, and rack spaces for physical
buttons and lights. Actually, a lot of their equipment is pretty
massive, especially when compared to current-day PLCs.
