Re: 9010 Z-80 Pod Help needed

Sounds like replacing the 6532 is in order (it's an IO chip). Those are
used in all the pods I think so you could try a swap and see if that fixes
the problem.

Subject: [Techtoolslist] 9010 Z-80 Pod Help needed

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
