Another CT60e not measuring up

[jvaltane]

I have trouble to get CT60e run in 060-mode. I'm able to boot 030-mode, but in 060-mode I got just black screen. It is kind of trying to do something: My multisync monitor makes noise when changing resolution and when booting in 060-mode Falcon changes resolution, but screen remains black.

Previously I was able to get it up and running lifting it up little bit and then putting it back in 'right' 'angle'. It has been like this since I got it, but situation went worse when time passed.

Just in case I have tested all easy ones: different power, cpu and memory. So looks like problem might be in CT60e itself or machine. I'm wondering if I have done something bad, like bend CT60e too much while removing it.

Machine does not have timing fix or bus acceleration.

Any suggestions what I should test next? Check/resolder connectors between Falcon and CT60e?

Test the CT in another Falcon if possible. If you don't have access to another Falcon I suggest to get in touch with Willy, he should be able to test and if necessary fix your CT.

I hope you're wearing your dog strap every time you play with that card. It's full of FPGAs and the FP part is a concern.

Flexing 6 layer PCB with large BGA/QFP chips on is generaly not a good idea. So if its not sitting perfectly flat, it can already be damaged. Also frequent un-plugging such a board on a long pinheaders Falcon has as CPU expansion port, introduces a lot of mechanical stress to the PCB as well.

I might have possible to test CT with another machine. I'll try to do that before sending card to Willy.

I have to admit that I might have forgot to wear wrist strap some times. I have tried to avoid touch anything else than green part of the pcb with strap or not.

Flexing is what I'm most afraid of.
