I received a ACA1233n-40 last week and i cant get it to work properly.
My A1200 has fresh capacitors and none of the mentioned possible culprits were mounted.
Its running Kickstart 3.1.4 together with a clean install of Workbench 3.1.4.
The card shows as "working" in the boot menu, and i can see the memory correct and so forth. But if i run anything half heavy like a game, or just doing a "List all" in the CLI, the machine reboots and displays a black screen, sometimes a guru.
I have the lib installed, and also installed the 68030 library to get rid of boot warning.
I map the rom without any problems.
The Amiga works fine without the accelerator in, and i have tested it in another A1200 running 3.1, still fails..
Is there anything I can try to make it work, or should i just send it back to the store that sold it to me?
