Hi,
I have an Apollo 1240/40MHz board for my A1200 and it was stable for years but since I have installed Indivision AGA the accelerator crashes with Guru. When I remove Indivision AGA then it is stable.
Motherboard is 1.D4 with budgie rev 01 (indeed rev 0 but the part namber has a -1 at the end) so the two capacitors (E123C and E125C) were removed by me long ago. I have replace PSU but still the same (using a 300W ATX PSU now but tried with 400W Corsair too).
Interesting is that I have tried to put back E123C and E125C and the system seemed to be more stable but still crashes.
Now I am planning to try the additional fixes but cannot find XR358 on the motherboard. Does anyone know where is it located?
Regarding the additional pull up resistor to Alice's pin 43 I have seen photos where the resistor is connected to the clock port's 5V pin2 but where is the other end connected to? Does anyone have a high res photo of a modified motherboard with this patch?
I have a feeling that these two patches need to be applied to 1.D4 motherboards even with budgie rev 1.
Thanks
Lapeno
