Historically, computers under the ''Elbrus'' brand comprised several different [[instruction set architecture]]s (ISAs).

The first of them was the line of the [[mainframe computer|large fourth-generation computers]], developed by Vsevolod Burtsev. These were heavily influenced by the [[Burroughs large systems]] and similarly to them implemented [[tagged architecture]] and a variant of [[ALGOL-68]] as [[system programming language]].

After that Burtsev retired, and new Lebedev's chief developer, [[Boris Babayan]], introduced the completely new system architecture. Differing completely from the architecture of both Elbrus 1 and Elbrus 2, it employed a [[very long instruction word]] (VLIW) approach.

In 1992, a spin-off company [[Moscow Center of SPARC Technologies]] (MCST) was created and continued development, using the "Elbrus" moniker as a brand for all computer systems developed by the company.

In the late 1990s, a series of [[SPARC]]-based [[central processing unit]]s (CPUs) were developed at MCST as a way to raise funds for in-house [[semiconductor intellectual property core]] development and to fill the niche of domestically-developed CPUs for the [[Backdoor (computing)|backdoor]]-wary military.

In June 2024, a new computer based on the “Elbrus-2S3 (Эльбрус-2С3) microprocessor”<ref>{{Cite web |title=Центральный процессор «Эльбрус-2С3» (ТВГИ.431281.027) - МЦСТ |url=http://www.mcst.ru/Elbrus-2C3 |website=mcst.ru |date=2021-08-23 |access-date=2024-10-08}}</ref> was developed by Roselektronika.<ref>{{Cite web |title=Ростех разработал самый миниатюрный компьютер на базе «Эльбруса» |url=https://rostec.ru/news/rostekh-razrabotal-samyy-miniatyurnyy-kompyuter-na-baze-elbrusa/ |website=rostec.ru |date=2024-06-13 |access-date=2024-06-26}}</ref><ref>{{Cite web |title=Ростех разработал самый миниатюрный компьютер на базе «Эльбруса» |url=https://rostec.ru/media/pressrelease/rostekh-razrabotal-samyy-miniatyurnyy-kompyuter-na-baze-elbrusa/#start |website=rostec.ru |date=2024-06-13 |access-date=2024-10-01}}</ref>

In September 2024, The MCST company presented “Elbrus-2S3 (Эльбрус-2С3) microprocessor”<ref>{{Cite web |title=Description of the microprocessor device and its operational characteristics - Central processor "Elbrus-2S3" (TVGI.431281.027) |url=http://www.mcst.ru/sites/default/files/u11/TVGI.431281.027RE_2023-05-29.pdf |website=rmcst.ru |date=2021-08-23 |access-date=2024-11-02}}</ref> at the 10th anniversary Russian forum "Microelectronics 2024".<ref>{{Cite web |title=Ростех разработал самый миниатюрный компьютер на базе «Эльбруса» |url=http://www.mcst.ru/2024-09-30_mikroelektronika |website=rostec.ru |date=2024-09-30 |access-date=2024-10-08}}</ref><ref>{{Cite web |title=Catalog of solutions based on the Elbrus-2S3 processor - 2024 |url=http://www.mcst.ru/sites/default/files/u11/Elbrus-2C3_catalog_2024.pdf |website=rmcst.ru |date=2024-09-30 |access-date=2024-10-08}}</ref>

In December 2024, Programmable logic controllers "PLC-Elbrus (based on the Elbrus-2S3 microprocessor) " of the holding company "Rostec Electronics" of the State Corporation Rostec have passed state registration and are included in the register of software and hardware complexes of the Ministry of Digital Development of the Russian Federation. This allows using the devices at critical information infrastructure facilities to create automated process control systems.<ref>{{Cite web |title=Промышленный контроллер «Росэлектроники» на базе «Эльбруса» прошел госрегистрацию |url=https://www.ruselectronics.ru/news/26466-promyshlennyy-kontroller-roselektroniki-na-baze-elbrusa-proshel-gosregistratsiyu/ |website=ruselectronics.ru |date=2024-12-11 |access-date=2024-12-14}}</ref><ref>{{Cite web |title=Каталог Модуль процессора МП21 |url=https://katalog-rek.ru/catalog/127/8441/ |website=katalog-rek.ru |date=2024-12-11 |access-date=2024-12-14}} - The MP21 module based on the Elbrus-2S3 processor is implemented in the Com Express Type 6 Compact form factor (95×95 mm).
