SAPI-80
Designed by Ing. Eduard Smutný, TESLA Strašnice.It was manufactured from 1983 by Tesla Strašnice. The computer was inspired by or was successor to Intel MDS 80. Hardware is based on MHB8080A, UB880D.Operating systems running on the computer: ISIS-II,CP/M.
Clone according to the possibilities of the component base, but SW fully compatible. even the description of the processor card SAPI-80/01 is 80% literal translation of the original Intel manual, MULTIBUS bus, the first boards had a bus controller from several IOs, later boards used a copy of the intel i8218 controller from the USSR.
SW is then on OS ISIS II, CPM, PASCAL80, BASIC80, PL/M 80, FORTRAN 80, MBASIC, MFORTRAN

Inaccuracies/doubts related to the topic
The model was an Israeli computer - a clone of the Intel MDS 80, not the Intel MDS 80 itself. The exact name of the computer is unknown.
