This is still a pre-Alpha version.

If you have memories or documents about the Mitra-15 computer, please can you share them?

A readme and repo that looks authored by an actual human. Congrats on shipping, that looks pretty cool!

So good project... Maybe put a link with histelfrance.fr ? I wonder which digital pabx uses the Mitra family, E10N1 ?

Ah, another "télécommunicant"!

I briefly worked on 11F centers back in the 70s and 80s, not E10 family, but in 1999, I salvaged some AM2901 chips from Mitra CPU boards that were headed for the scrap heap. They came from either the Yellow Pages or Transpac in Rennes facilities—it was a hectic time!

As for information sources, I found doctoral theses from CEA, a scientist from INRIA kindly pointed to INRIA historical resources and current work [0]. There are as well SNCF, EDF or BULL historical resources, a museum in Denmark, ex USSR documents but for creating a Mitra simulator nothing beats Pascal Chour's website.

What is missing for a SIMH simulator is original software to make sure the simulator is accurate (currently it is not).

Found the answer in the Alice Recoque Wikipedia page (the Mitra 15 designer). It has been used in the E10N4 digital pabx...
