So, I really need to upgrade my Z80 to Z80/AA , the regular Z80 just doesn't cut it when trying to work on Z80B @ 5Mhz .....

I believe you just change the cpu for a faster one inside the pod which is what I did with mine and it worked on arcade boards I was repairing, but I read if the clock speed is too fast then the UUT might not function properly in that case you need the Z80QT pod but just changing the processor turns the pod into a Z80AA Andrew Sent from my iPhone Please excuse any spelling or grammar mistakes as this was sent from my iPhone

The problem with swapping UUT CPU cables is they are simply not the same. http://flippers.com/fluke.html (near bottom is the list) What I found is that the different part numbers have to do with how the twisted pair wires are connected to the grounds. If the CPU has two grounds (commons) then BOTH lines in the cable are also tied together, and the twisted pairs for the data side of the cable is also tied to that common ground within the cable housing both at the UUT plug and the header where the ground are brought out to the pod ground tie point. This was for a 6502 cable #685479. Have not explored others, but assume similar rules apply. It looks like you can repair these cables if you are careful in trimming and crimping etc. The breaks I found were at the pod end connector and so shortening the cable by 1/2 inch should get you onto fresh wire but it will be rather fiddly work... However you can use a shorter 40 pin UUT cable that is not shielded/twisted as long as it is shorter than the regular ones for the higher speed CPUs. At least I assume you can get away with it. After all Ms Pacman (uses a Z80A) runs on a daughter board that is at least a six inch long ribbon cable... Your mileage will vary! John :-#)# On 2017/08/08 10:32 AM, William Stillwell wrote:
Actually just need to swap a few parts... but has anybody tried using the standard UUT cable?? or maybe i can take a UUT cable from one of my extra pods?
The directions are outlined in the Z80_Pod_Upgrade_To_Z80AA.pdf from Fluke.

I believe you just change the cpu for a faster one inside the pod which is what I did with mine and it worked on arcade boards I was repairing, but I read if the clock speed is too fast then the UUT might not function properly in that case you need the Z80QT pod but just changing the processor turns the pod into a Z80AA

Is there a way to upgrade a base Z80 pod or are there lots of EMI based differences between the two... Anyone in the know?

So, I really need to upgrade my Z80 to Z80/AA , the regular Z80 just doesn't cut it when trying to work on Z80B @ 5Mhz .....
So, either i need to upgrade it, or try to pry a /aa or /qt from someones hands.... no, im not trading my 68X09 pod :)
I may have some extra 6800 and 8086 pods.
