Specification:
For Amiga 1200 and ACA 500
Full 68030 inc MMU running at 25MHz (not overclocked)

Didn't purchase the ACA 1232 bypassed it as it is slower than the ACA 1231, which I bought through Vesalia as they were still making them.
 
Plus the RTC is builtin to the card no addon. Although the RTC addon is great if you want to use it by connecting it directly to the A1200.
 
Nearly hitting the 10K mark :-)
 
Would highly recommend getting the timing fixes done as it makes a huge difference have only had one game not work since getting the fixes.
 
Also got the cap's replaced and the sound is crisper/cleaner than it was sounds a lot different.. :-)

Thanks very much for your help ,can i do the timing fixes or do i have to send my Amiga off to say Amigakit,Brian

I have an ACA1232 @ 33MHz as well, and it's a damn good card. 7.97Mips with SysInfo, and plenty of RAM (128MB). I softboot KS3.1, as the 1200 has original 3.0 roms in it. All works great, can even play doom at a reduced screen size. :elvis:
Preloading huge CD32 games in WHDLoad is pretty cool as well (Darkseed). You'll need timing fixes though with any A1200 cpu card depending on motherboard revision. What's your A1200 mobo revision?

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

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

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.

 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.

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.
