ACA 1232 Accelerator with 128MB RAM

[ChaosLord]

Could someone with an ACA1232 and/or other related accelerator please run Bustest and copy/paste the text here for me to look at?  Thanx!

And you must state the exact video mode that your Amiga was in when you ran the test, in order for the test to be valid.  And tell us the Mhz of your ACA card.

If the ACA is as awesome as Jens says it is then it should produce really outstanding bustest results, but I will wait and see.


p.s. I have run Blizzard 060 50Mhz and Apollo 060 50Mhz in 2 A1200s and never needed any "timing fixes".  I never even heard of "timing fixes" before the ACA cards came out.

Hi its a 104 revision
 thanks for the reply,Brian.

A 1D4 A1200 motherboard WILL require a fix. See below link for information and instructions:

http://www.ianstedman.co.uk/Amiga/amiga_hacks/A1200_Mobo_fix/a1200_mobo_fix.html

My ACA seemingly worked fine on my rev.2B A1200 without the fix. But with WHDLoad on some games I had freezing problems, or graphics corruption. Like Breathless would freeze after 2 minutes, as did AB3D after a while.
At the time I read over at eab that Mad Professor Mariarti was a good game to test whether timing fixes are needed and whether (after fixing) fixing was successful. I loaded the said game...before the fixes the graphics became trashed in the intro...so I knew I needed fixes. I performed the fix and hey presto...no graphics corruption, and no more freezing either on those other games I mentioned.

As for the timing fixes with non ACA cards, the problem is not a new one and not unique to the ACA series. Not all A1200 motherboard revisions require the fix, so that's why a lot of people never needed the fix to begin with (back in the 90's for example). AFAIK it's only the 1D4 and 2B motherboard revisions that require these fixes, and yes, even non ACA cards (not ram expansions) will require the fix as well in order to work correctly.

Thanks to all for there help ,still not sure if i have done the right thing ,but having aE-Matrix 1230-50 Accelerator Card years ago i had no problems apart from i remember some thing being loose on the underside of the board or was it the top side ,so i pushed it back in and never troubled me again,so i have bought a E-Matrix 1230-50 Accelerator Card ,and i was hoping i would not have to fix the timing

any way thanks again.Brian

 Hi thanks for all the info ,very interesting but i have gone for the E-Matrix 1230-50 Accelerator Card ,i had one a long time ago and i was very pleased with it ,i will let you know how i go on with it after it arrives ,very best wishes Brian.

That is not 100% factual.

That is not 100% factual.

my NOS 1D4 came from Amigakit and it looks like those components were never populated, so some did not need the fix.

Yeah a lot of ppl repeat information the see elsewhere posted on the internet. Its kind of funny how nobody needed "fixes" until these ACA cards came along..

There are posts prior to the ACA cards re these issues. Google is your friend :-)

[magnetic]

Yes not even close to 100% actually. The point was is I know many a1200s running for years now with all kinds of diff cpu cards. This whole "timing fix" thing really became popular with the introduction of these aca boards afaik

[UberFreak]

I needed to do these fixes on both my 1D4 and 2B motherboards to get a GVP 1230 and Blizzard PPC working properly.
It is nothing new.

I have a e-matrix in a Commodre 1200 I bought 18 months ago from a boot sale and had no problems!  In my old miggy (another Commodore) I had to get it fixed when I upgraded from a blizzaed 1220 to an Apollo 1240/40.  I think Amigakit did it for me back in the day (if they are the same Kingston based company).  Miss the old miggy - towered with lots of gubbins and was excellent fro Doom etc

Well that is good news ,i hope you are right,as i too had a e-matrix years ago and that ran like a dream and i was well pleased which is why i bought another one ,just wondering where more memory can be bought from.

I speak from personal experience. I never repeat "stuff I see on the internet". I have other Amiga 1200's. I have a 1A with a Blizzard1260 (doesn't require a fix), I have a 1D3 with an Apollo 1260 (doesn't require a fix), and I have a 2B with an ACA1232 (did require a fix). The ACA1232 will work fine in any A1200 board revision except for 1D4 and 2B. You could also say the same for a lot of other accelerator cards (like Havie's Apollo1240 for instance, and UberFreak's GVP1230 and his ppc card).

Amigakit more than likely did the fix for you before dispatching your A1200 (they don't want returns or hassle I suppose).
