Oh my god ... it currently is with a Vortex Golden Gate 486SLC ...
This card is either a diva or a b***h ... both in the worst meaning.
I bought it as dead, but optically it looked quite well. I put in one of my Amiga 2000 test setups and ... of course it did not work. But I saw that it activated the Zorro/FPGA part.
So I first tried to fix the "common" problems with this card: Cap between pin 12 and 14 of the MC68000 and I replaced the memory with a working one (tested in an other platform) and .. of course it did not work. But I heard repeated noises from the built in PC speaker, which I interpreted as the card trying to initialize the PC side. But the Amiga always froze so I always reset it ... which turned out to be a mistake:
One time I did not reset the Amiga but had to do something else in the meanwhile and I saw that with a delay of about one minute the mouse pointer was still moving. Then freezing again. Moving the mouse led to a delayed movement of the pointer on the screen ... After about seven minutes: The miracle: The PC speaker beeped and I saw the BIOS setup screen the first time! And ... of course the whole thing was frozen again ...
But each time I did a warm boot an started with "digger min set" again, I made a little progress and was able to configure and save more and more parameters in the setup. The more parameters (e.g. floppy disk config and hard disk auto detection) were configured the faster the card did "boot" until finally I could run digger after cold and warm starts of the Amiga without delay. The Golden Gate always did boot up and I was able to install DOS 6.22 and run all checkit tests without problems.
I was "high" and extremely happy, as a had paid quite a lot for the bridge board!


It could have been such a happy ending ...
But I wanted the card in my "one and for all" Amiga setup, so I transferred it from the Amiga it was working in into another Amiga. And (of course ...) I split up the original Amiga 2000 test setup again ...
In the new platform: The card did not like to start up. Mostly I got those cannot coldboot errors ...
I really tried for weeks - but no success. I tried to reproduce the original test setup ... no success. I tired in other setups - no success.
Most of the time starting digger or gg lead to one or several of these crackling noises (which in my opinion are "dysfunctional" initialization beeps of the PC side) and then does nothing. The next start of digger or gg (except for the parameter info) gives the coldboot error ...


So what is the status of the card now?
I have a suspicion: When grabbing the card and pulling it from and then pushing it into a slot again, I mechanically do change something on the card. This suspicion stems from the fact, that each time I move the card, it behaves slightly different: Only on crackle ... no coldboot, up to twelve crackles ... no coldboot, and sometimes I can reach the setup again!
So I know the card can work! I know that it has worked (for about two weeks, when I first made it work and did not touch it except for connecting a floppy disk drive and a CF Drive as harddisk). It worked then even with an ISA Tseng ET4000 VGA card.
But I was not able to identify the problem after I moved the card into other setups. I did e.g. check all solder joints with a magnifying glass ...
The next I will try is to exchange some parts, which are likely to habe been "moved to much or too often" when grabbing the card. Like a transitor and the silver clock quarz (at least I think it is one as it does not look like a capacitor ...).
So in the mean time I am tossed back and forth between deep frustration and high hope ...
Such a bitch!
And why, why whyyyyyyyy ...... did I not upgrade the test setup at first?

Whyyyyy did I rip it out of a working system?


Whyyyhyyyhyyy
