Shame that this board is pretty much useless without its ram. I only have 2MB, but I configure it to load as much of the OS & libraries into that memory as possible, and leave the 16-bit fast on my GVP sidecar for applications. She does allright, like that.
It's basically a door stop with out the RAM card :-/ Sorry I couldn't help. I have another card here of different make/model which is also 030, needs a pin repair but before it broke I couldn't get the full amount of RAM to detect. But I think it's 2MB too, speeds the Amiga 500 up no end but it's nothing compared to the ACA cards. The ACA-1233 smokes it :-)
Some of these older cards are frustrating.
Going to have a huge clean up soon though and sell a lot of my Amiga gear and just keep the A1200T.
Although I will miss the ACA 500 + ACA-1233, but would like to focus on just the A1200T.
