Yeah, that's another downside. But I was referring to the fact that it isn't plug 'n' play with some A1200 mobo's. People on different forums complaining about doing a mod first in order to get it working properly.


I bought an ACA 1220 a while back and it didn't work in my A1200 (3.1 ROMs). Since the store selling it didn't inform me of the possible need for timing fixes, I returned the card and got a refund.

I fail to understand why the ACA cards are so finicky. I've used several other cards in that Amiga without problems, including a Blizzard 1260 from DCE. The idea of soldering on the MoBo when all my other cards work perfectly isn't very appealing. I know that Ind. Comp. is a one-man effort but if all other card manufacturers managed to bypass the timing fixes, why not IC? It's weird to me.

Individual Computers have done some good stuff as well. I've previously owned an X-Surf card which worked brilliantly, both the network side and the IDE controller.

Well I have an ACA 1231/42MHz I had to do timing fix on my miggy but wasen't so hard then just a simple line in startup-sequence and all ran like a charm, so im happy with it even if I did not know I had to do timing fixes before I bought it it was quite easy to find out.


No, the timing fixes referenced here are actual hardware fixes, which means that you have to do some soldering on your A1200 motherboard. It's not needed for _all_ A1200:s, but quite a lot of them seems to need this (and from what I've gathered, different MoBo revisions require different fixes). The ACATune software added to the startup-sequence will not fix any of these problems.

I had to do the rev 2B fix found here http://www.ianstedman.co.uk/Amiga/amiga_hacks/A1200_Mobo_fix/a1200_mobo_fix.html

Read what I wrote again. Two things, timing fix and add a startup-sequence line (for the ACAtune software).


Heh, sorry :) I read that as "I had to do timing fixes, it wasn't so hard (back) then (when I got my card), I just added a line to my startup-sequence". Punctuation, dear sir, punctuation! :)
