Finally the CPU reported 14 MHz in sysinfo and not in AIBB. Menu update UPD500p_V0127 is booting and tries to update, finds ACA500+decompressing.. initializing... and I wait and I wait. So I think the heart of the beast is ticking. I tried to play a game Blaze and there were ghost sprites in gameplay. I hope it’s not from ACA. Can I make further tests before I send her to you? New intructions ?

I'll try and ks3.1 test and then we'll see.

Sorry for the delay but fortune wasn’t with me.

First I tried to my spare A500+ motherboard rev8A, KS2.04.37, I tested the mb and it was booting ok without the aca card. Then I put the card without the dismo, also removed the under pins and set the jumpers in de-brick mode. With the aca card it wasn’t booting at all. Maybe one time it booted, I don’t remember, but after a few attempts, a Green Screen occurred! I removed the card and the Green screen remained. After that in my attempts a Dark Red screen like Brown also came. Bad luck. Ram chips beaten. Then I took another exactly the same A500+ r8A, KS2.04.37 and this time it booted Ok. And this mb always was booting.

In the new A500+ rev8 system started OK, but I couldn’t check that the CPU was running at 14Mhz, how can I check it? But I saw that in RAM added 0.5MB. Wb3.1 reports 459,408 graphics mem and 395,876 other mem. Note that I was using a Gotek usb drive for these tests and a Wb3.1 adf disk.

Showconfig from wb3.1, reports two types of RAM :

type $A, attribute $305, Fast and

type $A, attribute $303 Chip, in addresses $C00000-$C7FFFF and the second at $488-$7FFFF both 0.5 MB.

In Showconfig, Boards: None.

Sorry I didn’t manage to find a ks3.1 rom chip but maybe I will make one in the next days and maybe the boot CF will work and I can make additional tests.

I also tried to boot with UPD500P_installerV11.adf in Gotek but nothing

Also Amiga is booting with the same behavior AND with the DISMO on the card, showing always 0_ in the de-bric jumpered mode.

Is there any hope to make this aca work? Thank you very much for your instructions, tell me what else do you want to check.

If it cost 100 it is not affordable. The shipping costs are at least 40 I think and I can buy a new one plus warranty with 140€.

Can I send the card , then you check her and tell me a service price?

If the price is reasonable for me, I will tell you to proceed, else you will send it back to me.

How much will be the initial test you will make? Also how much the shipping to Greece ?

Thank you for helping me out it is a difficult case and I regret buying it.

(* but I think the beast in the card is sleeping and just needs a firmware to wake up *)

I know how hard it is to service and to repair these delicate things and your efforts must be paid well when spending hours.

I am sure you can work it out and it will be an easy fix now, just I have the feeling.

I dont understand what do you mean saying "gapless chain of proof in preparation for a lawsuit" but I am willing to pay whatever you want

because I want to make this card work and enjoy her with my Amiga, if the money will be reasonable. amount of course.

Just tell me what to do and how much it will cost, pm me in my email.

Thank you Very Much for answering me, and I promise you to make it as easy as I can for you, and everything will be ok.

Please help me to make her as new and I will take good care of her! Thank you.

This card has a new good owner. I don’t want anything free of charge or in a warranty. I just want to pay for repairing this card and also all the shipping costs is on me. It’s a pity, to throw it away, her optical condition is good, and I think she needs only a reflashing and it will be ok. I am sure you can fix it! Please Jens, give us a chance contacting me through my email sending me the payment details including the shipment address.

Thank you!

Dear sirs,

Thank you for your reply. I bought the card as a defective one so I knew she has problems, and the price was low. Can we try to repair the card ? Either replacing the dismo or whatever solution you are thinking ? Is it possible to send it to you for repair ? I can test whatever you want and send pictures if you want.

Thank you.

Hallo ,

I bought from ebay a used ACA500+ and try it tomy a500+ It comes with a black screen and sometimes a strange red or blue garbled screen and system is halted. The digits are showing after5 seconds 0_ and the last underscore _ is blinking.... The switch button has no effect.

What can I do ? I think it has lost the firmware but it cant boot to reflash it. Is there any way to reprogram it from jtag or remove the chip put in a programer and reflash it or from elsewhere ? what else can I do?

The switch had a problem and I replace it. I dont have a receipt and no waranty only the ebay buy. the only serial I have is ACA500plus ]142[ TT04W

I can check whatever you told me with a multimeter or an osciloscope.

Thank you.
