Here's a picture of the VME bus development board. It was a two board sandwich to support 10 chips in parallel (only one board pictured).

The first real-time HDTV encoders for terrestrial digital television (ATSC) were built by Harris using an IBM encoder chip. It took 6 chips to encode 1920x1080. The IBM chips didn't have an auxiliary bus, so you could see motion vectors limited to chip image boundaries (in this case, 6 tiles arranged like so).

I had a lot of fun there. The purchasing manager was a Scottish guy and he had an after hours drinking club in a small conference room with a wet bar. I was only 24 years old and working crazy hours. I'd get a few beers around 7 pm and then go back to work writing 8080 assembly language code for a few more hours.
I also ended up smoking weed with the CEO and CFO a couple of times. The CFO was not a young guy. I'm not sure how old he was, but he had all white hair. The CEO gave me a mason jar full of his homegrown weed as a gift when I finished the project.
That company and even the building is long gone. It's now a Google parking garage.
I'm not sure if they used the 8" cartridges all the way to 2005, but I can find out. I'm still friends with the original system maintainer. I pivoted to video compression in 1993 and lost track of the program, but we found each other on Facebook in 2010.
