Well, resoldering (reflow) all main IC’s might help. Have you got or got an access to a hot air gun?

Yes, I do. I have a hot air soldering station but it didn't help...


(obs: are you looking for a TK95 from Microdigital?)

I have a dead one, for sure it was due to a bad connection to the bus expansion.

I have no information how to fix it as Dan never answered any of my e-mails.

Do you guys think it is possible to fix it?

I think, my dear friend, that you should use the hammer to repair the If1bis :)

Yes, I thought about that... :)

It is a very rare machine in Europe, and getting it from Brasil is quite expensive: delivery cost, taxes and currency conversions almost double its price :(

Yes, I do.

Regarding your IF1bis, the CPLD or the main PIC could be faulty. In the second case, trash the interface and forget about it. If the CPLD is faulty, replace it and re-programme with the files available on the Dan's website.

I have a friend here that probably can sell you one TK95.
I will replace the CPLD. But before doing it is there any test/measure I can do on it to make sure it is bad?

Thanks!

You can try to communicate with the CPLD by using Xilinx iMPACT tool. Then read the content and compare the downloaded file with this one available on the Dan's website. Any failures in communication with the CPLD could indicate issues with the chip. Before you replace it you can try to re-program the chip.

Good luck.
