Maybe someone has mention this before but..


Also check the CIA 8520 chips.  

The CIA A handles mouse and joystick ,keyboard signals.

They are the first I check if an Amiga goes crazy .

These chips has given me some strange errors over the years :madashell:

If they are socketed, try to switch them.


Happy hunting :)

If my memory serves me right it's U300 and U350.
They are located in right top corner(under the powersupply) if looked at the front of the computer. They are the same chip and place side by side.

They are surfacemounted from the factory , but I always solderes sockets when they where broken. Easier to replace :biglaugh:

Hope this help's :)

Do you want the pcb or a fully populated board with all the trimmings?
If it's a single layer it's easier to copy.

I guess the only one who would care is our "friend" Amiga.Inc ?
Due to their naming rights..??...
And I hear they are very easy to contact :lol:
