Rebuilding a Gameplan MPU-1
SirPeale:
I'm not worried. It's well documented, I just need the schematic. I see references to people having it on the 'net but so far haven't found it. But I've also given it about two minutes of searching.

Muchas gracias!
I've removed two sockets. Man those things are a pain. I'm just glad they're in bad shape (as strange as that sounds) as it made the removal process a lot smoother. Fixing the holes and whatnot should be fun...
lilshawn:
i find on allot of those old boards, using a dremel with a cutoff wheel to chop the ic's legs off right next to the chip, then using needle nose pliers and the soldering iron to take the stumps out, makes things allot easier....and less likely to rip of a trace because a leg is still semi-attached to the board.
it's easier to do it one at a time than to try and get all 20 at once IMO
ChadTower:
The dremel throws little metal slivers around. Be careful there. It's also a LOT easier to bounce the thing and gouge another part.
