For me there are two constraints.  Information.  Time. Certainly a 
chapter about Ceres would be desirable.

The easiest way is for someone with a working Ceres to donate the boot 
software. I don't know any individual possessing a Ceres.  Probably a 
few remain in Europe.  The Computer History Museum has more than one.  
A person living near the museum can become a member and initiate 
restoration of a Ceres to working condition.  Then the boot code will 
be accessible.  If you want to take a sabbatical year or so in 
California, there is a nice possibility. I live beyond commuting 
distance and can not volunteer for such project.

The Oberon sources are in the original Project Oberon book.

Another possibility: the Web site you mentioned has an interesting 
page describing computers built with wirewrap and with breadboard 
wiring. http://www.cpu-ns32k.net/Gilbert.html Hypothetically, there is 
a possibility of recreating a Ceres machine.

A further possibility: the Web site you mentioned has an interesting 
page about implementing(?) a NS 32xxx in FPGA.
