Happy days. So if there is a broken leg on one of the custom chips then you can solder another leg from a donor chip if it has enough metal exposed. Some people use a dremel to expose more of it if its snapped at the base of the chip.

Thanks, but luckily the CIA sat in 2 other ic sockets wich had a switch so 2 pins were soldered from one socket to switch and also on the next socket, so if you switch it probably made the external drive as first boot drive.

I guess.. Because when i bought it, it had a external drive.

So the pin broke off from the last ic socket.

 

Also the drive does not fit firmly in the amiga case so that is probably the reason i guess, in that time there were no goteks.

 

But i am going to fix that.

 

Other question, what is the best way to remove the rusty corrosion on the metal plates in the amiga, because it was on a dry place but it also was not airtight all these years, so humidity had it chanche to do it's work.

I do not want to use steelwool.

 

The guy wich i bought the other one from uses baking soda...

I even want to try elektrolysis, because i have a lab psu.

Baking soda will work. The important thing is to paint them after cleaning or they start rusting pretty much straight away. I used PCB lacquer after wet sanding the metal plate of the a1200 keyboard. 

 

But there are better ways.
