Interesting one, I think this is the first manufacturing arm in the collection :)

I'm intrigued by the diagrammatic characters in the first 16 codepoints, I wonder what kind of schematics they were used for...

If you're interested in the hardware, here's the little I've done with it. Eventually I may try reverse engineering the memory map and getting it to run something else since I don't have the actual arm. https://www.origamiparade.com/hardware/ibm7535/ibm7535.html
