[Techtoolslist] 9010 Z-80 Pod Help needed

[Justin Johnson]

Hi Guys,

I'm hoping I can find some help fixing my Z-80 Pod.  Here is the  
scoop and I will try to make this short.  I purchased a Z-80 pod with  
the cables cut off.  Found a new set of cables and tried a self  
test.  The self test gave me the failure code 00.  I then used a 40  
pin socket and removed pin 29 as suggested in the manual and placed  
the socket on the pod pins and reinserted the 40 pin connector into  
the pod for a bus test.  I then got a CTL ERR 00000000 00001000- 
LooP.  As I understand it that shows an issue with driving bit 5.  Am  
I correct that this is address and data line 5? I used my logic probe  
and probed the data lines of U4 or R6532AP.  I found that pin 28 of  
U4 which is the R6532AP has Data line 5  low while the other data  
lines are high.  Where do I go from here?  Any help or suggestions  
would be appreciated.

Thanks

Justin
