I have compared the pinout of the MM58167 with the diagram given in the
Ceres-3 Hardware description ...
... unfortunately, these are completely different, so your assumption
seems not be valid :-(

A comment on book said:

For me, 'National Semiconductor' and 'RTC' together mean their own
design of the MM58167 that was used on the AST multi-I/O and memory
expansion adapters
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 ...

It may also be useful to contact the CS/EE department(s) at ETH and ask them.
Perhaps they have a copy archived with the project
Thanks for the link ...
... i will ask him if this my help.
Thanks Bernd
