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 :-( Liam Proven via cctalk wrote on 13.04.23 15:38: On Tue, 11 Apr 2023 at 17:41, Bernd Kopriva via cctalk wrote: Does anyone have a pointer to the datasheet ?

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 ...

The "easy to find" documentation for the Ceres-3 was not helpful but he is tying to get in contact with one of the "older" guys that were involved in the developemnt Will Cooke via cctalk wrote on 12/04/2023 15:48: On 04/12/2023 8:26 AM CDT Bernd Kopriva via cctalk wrote: Thanks for the link ... ... i will ask him if this my help. Thanks Bernd 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 documents. Will
