This is a renaissance of the "Specialist" micro-computer published in the popular "Modelist-Constructor" magazine issue #2, 1987 by A. Volkov.
The original design was used the Soviet i8080A analog - KR580IK80A (KR580VM80A), but this one is based on the Z80A CPU.
Postfix "S" in the project name designates a "simple" design.
SECU86 is Standard Engine Control Unit x86. The project goal is to develop a standard computer and OS (opensource) that would work on any car. It'll be based on the x86 processor and will try to replace the poor standard ECU that comes with any car.
