ACA1230 timing fix
I've just plugged my ACA1230. First and second bootup were successful, but now IPrefs and Amidock usually crash at the very beginning, then the workbench crashes(usually), so I can't even install the ACAtune. Is it about this "timing" thing? I've got a rev2b mobo and I'm not sure if I should remove these two little 123 and 125 things from the backside of the mainboard?
thanks |

Hi BX20,
Did you buy the card new? If so I'd suggest contacting your reseller for advice. Here is some more info on the Timing Fix that was supplied in the ACA thread by Jens of Individual Computers. http://eab.abime.net/showpost.php?p=...postcount=1359 All the best, Steve. |

FOL,
I have done the timing fix. As soon as i remove the ACA1230 and for example insert my Blizzard PPC, Amidock works like a charm. |

Is it only Amidock that locks? If so, it sounds more like Amidock has issues rather than the ACA...

Amidock is a pretty slow tool if you ask me.
BUT, i have 4 other accelerators, no one crashes when Amidock is placed in WBStartup except ACA1230/56. This is not a big deal for me, just letting BX20 know that he is not alone with the problem. |

Thats the old timing fixes. Jens spent alot of time investigating the whole timing fix problem.
He posted an update to the E123 and E125 fixes. You change a few components and add a few. Last edited by FOL; 09 August 2011 at 11:53. |

Can we have a link to this second fix?
I think the info should really be on Jens Website, I still can't even see ACATune on his site Any chance of adding it to the Amigakit site so we've at least got somewhere to link? Steve. |

Off the top of my head, E121R and E122R need to be changed to 60ohm Ferrite Beads. E121C and E122C need to be added (iirc 22pf). Only E123C should be removed (insome cases you need to leave it). E125R,E125C and E123R should be present. Sure Jens will correct me if Im wrong. |

the best way to test if the A1200 mobo timing is correct or almost correct (with or without accelerator) is testing Krisalis games like
Arabia nights Soccerk kid AGA or ECS......(check if music works) Sabre team Mad Professor Mariarti ( check if music works) these games requires correct hardware timing to work if none of them works or partially works without music you have serious timming problems the capacitor' hack did not solve timing fixes in most cases |

After doing Jen's new timing fixes, I can assure you it fixes all timing issues.
Remember we are not just removing caps, we are adding caps and changing some components. Accelerators and RAM boards that never worked on a board, worked fine after applying timing fixes. I think your talking about something different? Maybe CPU cache issues? |

I'm talking about that games above are affected by timing issues....if timing on the A1200 is not correct...those games will not works fine.....lack of music or will not work at all...and it doesn't matter if cache is turned on or off or if you play the game from hardisk,floppy or whdload.....those games will not works fine....they have bad code and only work with correct timing.....check those games on good motherboard and then on a motherboard with bad timing...you will see |
