Interesting. Unfortunately, I have no docs (outside of what's on Bitsavers).
Mine is the later 980A variety, FWIW, with fat TI4060 DRAMs not core.
I only recently got a console key for it.

The only spare parts would be some memory boards. I'll have to pull
them out and check them, but definitely DRAM and I think 8K or 24K
capacity, and I have no idea if they work on all variants or just
specific models. No spare I/O or CPU boards.
I was just glancing over at the docs on Bitsavers to see what it might
take to write a memory tester to toggle in. Nothing exhaustive just
simple write-read-compare testing. I know nothing of the architecture
so even that would take me a bit to figure out.
