The setting of DIPSW is different from Zolgiar.
Check it.
MasterCPU PCB SW4 No5,6=OFF (Dragoon) / ON (ZOLGEAR)
Slave CPU PCB SW4 No1,2=ON (Dragoon) / OFF(ZOLGEAR) No5,6=OFF (Dragoon) / ON (ZOLGEAR)
Three personal PCB is same PCB.
As for a red lamp, the system works.
It is not possible only to operate it.
I want you to teach the state of LED of Master-CPU PCB.
If it is normal, LED 16 pieces all lights or it blinks.
Some hints might be able to be taught.
If the system works
There is a possibility when personal PCB and the communications error occur.
This is repaired in many cases by the change of IC56 SN75158 and IC60 SN75157.
Please consult if the change is difficult for myself.
