XSurf-100 and GRex4000D

steenlund · Dec 31st 2019

Hi,

Any one have experience using the XSurf-100 in a GRex? The card does not show up in the boot menu or Show config at all and I am wondering what could be wrong?

I am working on getting my hands on an original A4000D daughterboard to test further.

Cheers

Steen

Did you try closing the Z2 jumper? That would be the first thing I'd try, just to make sure that the simple (albeit slow) Z2 mode works.

Yes, that was the first thing I tried but still no luck.

I just wanted to know if there were any known issues as I don't have any other Zorro boards to test with nor do I have a original daughterboard, but I am working on getting my hands on some. Then I can figure out if it is my Amiga, a bad Buster, or the GRex

If even Z2 does not work, there's something seriously wrong with the setup. I'm afraid you'll really need the original daughterboard in order to isolate the fault.

An original daughterboard has arrived and I have replaced the GRex4000.

I had to pull the XSurf out just 1mm or so but then it worked in the original daughterboard.

Still no luck getting it to work in the GRex, even when pulled a tiny bit out of the socket. I will have to do some measuring to see if everything is correct on the GRex, I have a feeling it might the auto config lanes on the PCB that are faulty. This is going to take some time to debug.

Thanks

At least you have a solution that works as advertised - I'll mark this as resolved.
