In the process of upgrading my custom chips in my A3000 to latest revs.
Have Buster 11 and Dmac (latest rev) here, waiting for Dmac to arrive from amiga centre.
Now for the part of removing the chips, I thought it was as easy as when removing and upgrading the chips on the mediator boards but how wrong I was.
I used the same technique but the chips are quite stuck (lol?)
Anyone with a great tip on removing these little &%#x@!!!?
Or do I need a special tool?
-
Always use a chipextractor when changeing socketed PLCC chips. Never use a screwdriver to force the chips out as the chances of brakeing the sockets (and therefore rendering the whole board useless) this way are quite high.
Maybe you can utilise lockpicks to pull the chips out.
-
Too use to using brute force since I'm an outboard engine mechanic, hehe
Any idea where I can buy a chipextractor suitable for this task?
-
When I can't use a chipextractor then I use one of my crocked tools. Looks like an icepick but much smaller and it's crocked in a way that you can put it in one of the holes (where the chipextractor would go) and tilt it alittle, then the force would go into the motherboard and not on the socket.
Found the tools on "Rusta" I think. :)
-
Do you mean a lockringplier? (låsringstång)
checking Rusta's site now but can only find this plier which I don't think is thin enough at it's points to be able to grab the chip

Or did you mean a plier like this

@AMIGAZ:
This (http://www.elfa.se/elfa-bin/dyndok.pl?dok=/elfa/produkter/se/276123.htm) is what you need.

and its cheap too :-)
ELFA its really cheaper than RS-Components
-
Thanks again!
looks like I have to pay Elfa a visit, maybe I should buy a 66mhz crystal too for some serious 68060 overclocking ;)
Looks like I won't be able to upgrade one of the chips yet because the lame ass at Vesalia sent me a Dmac 02 instead of the super buster 11 I ordered!
Had a topic recently here about them and their crap service

This time I photographed both chips and sent the picture in an email, wonder how long I'm going to be ignored this time.

I am looking for DMAC-04. Where can I get one?

Hi,
in the motherboard of an A3000T, there are two small holes behind every PLCC socket. They are filled with solder, but it is very easy to desolder them using a sniffer to suck the solder away. I use small nails to press the chips out of the sockets and it works very good (and is much cheaper than an extractor, that is nearly as expensive as most of the custom chips).
If it is too late and you already have a broken socket, it could be fixed by stretching a wire or a cable binder around the socket that holds it in form (works great for me).

@Noster:
Elfa charges ~4EUR for the extractor. Definately worth it when it saves you from having to disassemble the computer completely to get access to the backside of the motherboard.

Will definitely buy the extractor.
Still waiting for the Buster 11 chip Vesalia didn't send me when I ordered it (grrr)
My A3000 has been blown wide open for too long here now thx to them.
-
Have you tried to ring Vesalia? Direct contact sometimes works wonders.
-
You mean to recieve the right things you order you have to call them? :lol:
I emailed them telling that I had recieved Super Dmac 02 instead of Super Buster 11, they replied with this:
We will include the DMAC 07 to your new order. Sorry for all the inconvenience.
Well, Super Dmac 7 doesn't exist at all! :lol:
Have ordered CybergraphX V4 from them and they told me that they would send the right chip this time in the same shipment (fingers crossed)
