Just bought a MegChip 2000

I just purchased a MegaChip for my A2000.  It looks like you pull the Agnus chip, and plug this in.  It has the 8735, and is supposed to up my A2000 to 2m chip ram.  I am just concerned about pulling the PLCC chip and replacing it with this.  I will buy a PLCC chip puller, but after all these years, who knows if the socket will be OK, or break apart.  Also, there is a jumper you have to attach to a pin on the processor, or on another chip, of which I can't remember.  How hard is it to get the jumper on the pin and situated so that it won't short against the adjacent pins?  I assume this is for clocking or such.  Anyone else have one of these?   Thanks.

BEFORE installing the MegaChip, wrap a nylon wire tie around the Agnus socket and tighten it snug. Do not over tighten. This will help keep the Agnus socket from splitting over time. Do NOT use the clip. Find a "thru-hole" that connects to pin 36 on the Gary chip or pin 48 on the 68000 chip and solder the wire from the MegAChip to this hole. It would be best if you remove the Amiga 2000 motherboard, so that you can solder the wire on the solder-side of the thru-hole.
 
If you do not actually NEED the extra meg of Chip ram, do not bother installing a MegAChip. It does put a lot of stress on the old Agnus socket, and if the socket splits, it is a major repair. So, do not let your ego cause you to damage an otherwise perfect Amiga 2000 motherboard.  In most cases, one meg of chip memory is plenty.

Well, I completely understand the theory of not installing it.  However, I bought the A2000 to play around with and learn about Amigas.  I was not fortunate enough to have been able to afford one when they were new, only the C64/128 stuff.  It wouldn't be in the spirit of why I bought it, to be afraid to upgrade it.  I don't use it for games and such, just to tinker on and play around with.  I do run AmigaOS 3.9 on it, sometimes, though, so I imagine it would help speed things up a bit.
