My old masterboard A16B-1010-0330/11A comes to senses only after heating of the part of PCB and operates. Axеs running.
Installed another masterboard A16B-1010-0330/10A shows "L" and on screen I see "PC PARAMETERS LOAD:END", though all additional PCBs(memory, etc.) works fine.
In what difference between 10A and 11A revisions?
