The Computer Automation CPU boards in the systems have been a complete mystery to me until recently. To make a long story short, I happened to stumble across the patent for the machine (https://patents.google.com/patent/US4254468A/en), which has the same bus configuration as my card cages, and also provides some good evidence that "Naked Milli" 3/05 CPU boards were used.

Bitsavers has been a great help in my efforts to uncover more information about this processor, but there's still a lot of technical information that has eluded me (such as the autoload ROM, and how its data is arranged). The LSI-series computer handbook mentions a dedicated manual for the LSI 3/05, but I haven't found anything else about it online.

This seems to be mostly about the Naked Mini 4. But perhaps you can find something useful:
