Amiga 500 1mb chip ram hack

[countzero]

I am interested in doing this 1mb hack for the a500. I had a dead rev6 board (it was booting, but doesn't read anything from floppy), so I got the rams from there. however, later I realised that my soldering iron was 60w. And I think I damaged some of the memory chips. So I'm not sure if I should go on installing these chips into the working board. what should I do ? Can I find other chips from other hardware ? Has anyone done this hack before ?

Best thing is probably putting some sockets on the empty places. i did this once, one mem chip was bad. Frustrating as h*ll to rip it out again. If you just solder in some sockets you can easily switch the ic's if one of them doesn't work.

Sockets are good. Yes.
If you want to get fancy, get the machined pin ones. Personally I prefer the standard ones.

Are you getting the dead chip ram error on startup?

Wasn't there more to just soldering in 4 more chips and cutting 2 traces?  Like adding 4 more caps or something?

[countzero]

yes, do i need to add 4 more caps ? I'm not(edit) sure what is a cap, but there are orange like diode - thingies for each original ram chip. do i need to add those as well ?

and how does the dead ram error look like ? power led blinking ?

For shure you have to add some capacitors.
The orange ones are ceramic type caps, I guess.
