This. I worked on satellite control systems in that time frame on these exact boards (OSE and VxWorks); at the time they were considered incredibly powerful for space applications. It was quite the step up from other embedded systems.

In comparison I've read in an article that spacex explicitly decided to use redundant of the shelf computer hardware in their spacecraft and rockets, citing huge unit and dev board costs and lead times measured in years. So far it worked fine for their near Earth applications and it will be interesting to see how they will handle long term deep space in this regard with starship. I guess they could still fly a rack encased in lead given the scale and performance of Starship though. ;-)
