I just received a ACA 1233n from Amigastore Spain, but i am having some stability issues.
I am getting random crashes with WHDLOAD games/demos that worked fine before on my old M-Tec 1230-50 E-Matrix.
I did a test with Systest 1.2 and every time i do a memory test for region 40000000 - 47dfffff (fast 126 mb) the system locks up and needs to reboot.
It looks like this memory region is the ACA card, i also tested the Amiga's 2mb chip and that passes fine.
My system is a A1200 1b4 with timing components already missing from factory.
Here's the data on screen where my system starts freezing up.
Single region memory test
400000000 - 47dfffff Fast 126.0 MB
Round 1.1: Random Fill
I reseated the card a few times but there is no improvement.
Also on a side note, it seems the ACA1233n is too small for the slot, when seated it points up and it seems it almost touches the underside of the metal keyboard.
