If all connections are good, I would remove both chips and then solder one of the new chips in place of the old working chip to see if they work at all.

OK. Well, after much thought, I tried that, and it did work. Only recognising 512kb still though.

So I removed the first chip that I soldered and put another one. And, I am I shocked! It works!

That's the first time I have managed to fix a computer by replacing a component. I am chuffed!

Thanks All!! I really appreciate your help and guidance.
