Hello all,
How hard is it?
It's the easiest upgrade you can imagine on the inside of a computer. Take a small flat bladed screw driver and carefully pry the chip out of its socket. Don't lift one side of the chip out of its socket all at once or you might break some of the pins, but alternate sides and lift it bit by bit. The code word is 'careful'.
When you removed the old chip, carefully align the pins of the new chip on the socket and push it in. Mind the orientation of the new chip as it needs to be the same as the old one. Don't turn it around or you might damage it!
The thing is, I am not sure which chip is the real kickstart on A500. do you have a picture of motherboard which clearly shows it?
The most important chip sockets on the A500's motherboard have their function written on the motherboard. Look for the socket named 'ROM'. That's the one you need.
Do I really needs this shield, if I am keeping my A500 at room-temperature?
No.
Oh, and is 1.3 THE most compatible Kickstart, or should I stay with my 1.2 on my A500?
If you're looking for games, 1.3 is by far THE most compatible Kickstart.
