Error 188

(1/1)

VMK:
Good day!

I have a problem with my Zendrum (ZX).
Led display always shows 188.
I tried to change the battery, but it did not help.



Then I disconnected the wires connecting the "motherboard" and cursor switch (see image).



Zendrum works, but it is impossible to configure.
What happened?

Inspector 109:
That's vintage stuff...94/95/96 Datawheel, so I'm trying to jog my memory about the pinout connections on that circuitboard.
Did you unplug the display ribbon? Something about that arrangement looks funny to me...
but I may need to get an older board out and put it on the bench to test my memory.  :o
Please reply directly to my support email and I'll try to help quickly-
