[Coco] CoCo2 PAL version service manual

[Zippster]

The one I linked has a hot air wand that blows hot air for melting the solder
on smd parts(not a vacuum).  For desoldering dip chips I’ve been using the
destructive method of removal (cut all the pins and remove one-by-one with the iron).
Then putting a socket in with a new chip.  I guess I’m more concerned with not damaging
the board than trying to save the chip.

The solder vacuums look interesting though, even if the good ones seem pretty expensive.

I bought a fairly pricey one the other year (Circuit Specialists 'BlackJack') and the desoldering piece is next to worthless.  Clogs repeatedly and doesn't have enough moxie to deal with ROHS solder.
