SM 50/50
It was manufactured from 1982 to 1988 (development 1980) by ZVT Námestovo. The computer was inspired by or was successor to PDP 11/23. Hardware is based on Am2900.Operating systems running on the computer: DOS-RV,FOBOS,DEMOS.
This topic deals with the SM 50/50 designed by VÚVT (Research Institute of Computing Technology), there is also another computer designed by SAS ÚTK (Slovak Academy of Sciences, Institute of Technical Cybernetics).

The SM 50/50 S was a conversion of the 16-bit microcomputer SM 50/50-1 into a demanding environment
Inaccuracies/doubts related to the topic
The PDP-11/23 is a QBUS system, so the predecessor will be wrong.
