I don't believe you mean the same thing as I mean when you use the word "easy"...

Compared to desoldering that, it is easy. ;)

(And I'm assuming you have a mill, not trying to whittle it out with a dremel or something; that way there's no risk of going to deep, just drop it 0.005" at a time, and stop when you can see the contacts. For anyone who does have the equipment, it's genuinely easy.)

The easier way to do this sort of stuff - and i've done it myself with an smd connector during the 770 era, so it _is_ easy - is to use a hot air rework station. Again, not the cheapest tool, but it works and if you have the right tip, you can do a relatively neat job.

It's fun if you don't mind playing with a smaller scale version of a paint remover.

Fair enough; I suppose those are cheaper than mills. I was somehow mentally excluding doing things the right way. ;)

I think I had to cut couple tracks on the motherboard as well. It was very exciting to turn on the machine first time to see if it still works... and it did!!! :D

Oh well... that was about 20 years ago... :eek:
Wow! I remember that! :) I was so glad, though, later when I started buying STe's and they used SIMM cards instead of having to deal with DRAM chips and sockets or any desoldering like the older ST's. I also remember upgrading my TOS chips that way on the ST's too! heh.. hell of a way to upgrade an OS, eh? But at least those old ST's booted up INSTANTLY into their OS, unlike most modern computers.

Of course you'll need first an announced Tegra device. :)

I borrowed one of these intending to hack my zaurus 6000 with more memory and a bluetooth module, and accidentally broke a ram chip; being BGA, it proved unrepairable.
