This project of Ceres on FPGA by Udo Möller was mentioned many times
on the list.
There is some good news on it.

The Ceres-3 is finally working on an FPGA board featuring a Verilog
version of the NS32k CPU used in the original hardware:

At "The Web Site to Remember National Semiconductor's Series 32000 Family"
http://www.cpu-ns32k.net
you can find many retrocomputing projects that Udo Möller has built
along the years,
http://www.cpu-ns32k.net/TITAN6.html
http://www.cpu-ns32k.net/TRIPUTER.html
featuring his own reconstruction of the NS32k family of CPUs
functionality in Verilog based only on the documentation manuals of
the chips.
His design is called the M32632,

and it is working on a series of Altera FPGA boards,

that anyone could use:

I even port one of his initial versions of the M32632 to a Xilinx FPGA
(Digilent Nexys4 board) but not the complete Ceres-3 project.

I hope you find this news interesting.
