The company could not help ...
... i'm not sure if the sources will help as he is doing a FPGA
implementation. The goal is to run the code in the original ROM ...

Hi,
a friend of mine is currently working on a FPGA implementation of the
CERES-3 workstation (cpu-ns32k.net/TRIPUTER.html#Ceres).
He currently lacks of information of the RTC chip M3001 which was
manufactored by Swiss company Microelectronic-Marin.
Does anyone have a pointer to the datasheet ?
Thanks Bernd
Did you try the company itself ?

Also the Ceres source code is available. I have assembler source for
the bootstrap of the Ceres-1 system.
