I am making a call to all the #USSR #Soviet #SovietUnion and #retrocomputing people (please boost)

I am interested in #Soviet computers (specifically the #Agat, #Minsk, #Poisk, #Iskra, #Setun and ES EVM + ES PEVM), however I can't find (with the aforementioned limited knowledge) much info on where I can find ROMs of the original machines. I want to emulate those and see how well they work on the cloned CPUs. I am also interested in the aforementioned CPUs (K1810VM86 mostly, but also КР580ВМ80А and КР1858ВМ) and the specific quirks these had over the Western CPUs. I am essentially looking to know all about these systems, and try to emulate them. Can someone guide me to resources and ROMs for these machines? I'll go through the hassle of translating myself, but as it stands I have no connection to Russian-speaking people.

Спасибо вам и хорошего дня!
