AW: Problem with MM V
 

Ich würde das Teil wenn möglich zurückschicken.

I would send the part back if possible.

Re: Problem with MM V
 

Sadly I do not have another modular board to try.

These 2 points on the board have a hairline connection. Do they have to be connected nor not in your experience?

Eprom corruption is possible because when I first opened the module, one side of the Eprom was slightly raised but of course I had already tried to run it.

If any member in the forum is willing to help me with a
pre programmed eprom, I will gladly pay for it.

If I purchase a new 65C02 from ebay, does it matter
if the speed is higher then 3MHz or try to get the same speed.

Thanks again everyone.

You should clean everything a little and then rework the critical soldering points with a soldering station, not with a normal soldering iron at mains voltage! Static Overvoltage possible.
However, the right of return would then expire.

Hi Udo,

the seller issued a full refund and asked me to keep the module.

I don't own a hot air soldering station. Perhaps I should get one.

I like to get this module working. I will order a cpu first then
I will try to get a pre programmed eprom from a member here if anyone is able to help with it.

All the best
Murat

Then everything is fine. I didn't mean a hot air station, but a normal soldering station.

Meine Güte, sind halbwegs vernünftige Lötstationen teuer geworden!

:eek:

Was ich noch anmerken wollte, eine Lötstation für Elektronikarbeiten sollte einen ESD Schutz haben.

"Protection against electrostatic discharge".

Oder eben tatsächlich mit Heißluft. Womöglich ist Heißluft besser, um einen kompletten Chip auszulöten. ?

Hier noch zum Abschluß 2 Beispiele
