Title: 2x 4MB S3 Trio PCI graphics cards with no RAM
Post by: motorollin on July 14, 2007, 10:42:13 AM

I bought these cards on eBay and removed the socketed RAM chips for installation on my CV64. The cards are now useless to me. If anyone has any use for them, maybe if you can de-solder the remaining RAM or if you have RAM to put in the sockets to make the cards useable again, then they're yours for the price of postage.

If I don't hear within a week they'll be binned.

Hi,
maybe the people need to know the references on the present chips  ;-)

Damn I destroyed mine long ago when replacing it with another card,there aren´t any outer damages,so any chance I could get it to work again?

motorollin, may I ask why you installed this ram on your CV64?  Was this to improve performance, or perhaps the ram was faulty?

Cheers,
James

@ jmbattle

In case moto is away for a while, it's an interesting read all about it in his thread HERE (http://www.amiga.org/forums/showthread.php?t=30178) :-)

Not sure if you still have them cards Motorolin', but here's a "trick" for the lazy-to-desolder:

Take a sharp-ish knife and try to cut the chips at their legs. Because you don't care about the rest of the card (I assume this is true anyways), you can use the card as a "guide", so you're basically angling the knife at around 45 degrees from the card and towards the base of the chip legs. The card surface will get all scratched up, but before you know it you'll have the one side of the chip cut clean. You repeat on the other, and then you'll have those "desoldered" chips on your hands. Just clean'em up a bit, maybe with a file if there are any sharp edges, and maybe straigthen out a pin or two that might have been bent, and they're as good as new. Used to do that years ago to upgrade *socketed* (that's the trick, coz these chips can't be easily soldered once they're cleaved) PCI cards with more memory :)

Good luck

@jmbattle
I installed the extra RAM to allow larger screenmodes which require more video memory.

The cards are gone now - sorry if anyone wanted them.
