Hello.
I have two card cages out of a pair of Linotron 202 phototypesetting machines, and have
been hunting for documentation for the Naked Mini systems used in them for over a year
now. 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.
I've found documentation for the LSI 3/05's instruction set and an informative
brochure, but nothing technical. 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.
If anyone has any information about the LSI 3/05, or where I might look for the manual,
it'd be greatly appreciated.
Thanks.
Hi
This seems to be mostly about the Naked Mini 4. But perhaps you can find something
useful:
