Removing soldered components

[jjans]

I wish to remove some ram chips that are soldered onto an old A500 motherboard.

I'd like to reuse them by installing them into my A590.

Any ideas on how to do this without damaging the chips?? :-?

Hey I LIKE that technique! Sort of similar to my original 'Red Green' style of using a hammer, a chisel, and a plier(and a case of beer). This technique works GREAT on WINDOZE machines...

Thanks for the suggestions, I'll try them on some old PC cards I got first...

Well I bought the solder sucker and it worked great. Thanks to all for the advise. I also gotta blow torch for an old PC card for fun...

I removed the 4 x 20 pin RAM DIP chips from an old A501 expansion card, and installed them onto my A590's card, and it worked great.

Still having a couple of dip sockets still open, I got even more exited, and ripped open another A501 card (and discovered a leaky battery...) and also discovered that this one used 16 pin RAM DIP  chips.

I now know the difference between the 2 A501 cards: Rev 5 (64 Kb chips) and Rev 6C (128 Kb chips) .

Both my A500's are REV 6A motherboards, which also mount 20pin 128 KB dips.

For my UFI fill for the day, does this mean the REV 5 motherboards mount the 8 x 16pin 64 KB Dips?

Better still, you think one could sew them together some how, in order to use them in the A590???
I know what you are thinking...
What a freakin' 'DIP-CHIP'
