Also one more tidbit with the LC-I

I added ram to a LC-I from another bad LC-I, Populated the empty pads. (used my new heat gun)

Afterwards, all i got when powered on, was the chime of death and no video. Removed the ram chips I added, and it started to work just fine.

I am wondering if maybe trash80 is right and there is something with Addressable space and Firmware in ROM.

So………. Being the relentless guy that i am …

I popped those LC-I rom chips out, installed LC-II rom's and it works!, So then i used the heat gun again and re-installed those other ram chips. and the chime of death, Again… So took those ram chips back off, popped the LC-I rom's back in … made it like how it was, and put it back on the shelf.

Enough fun for one day

So to recap, adding more ram chips to populate the empty pads with my LC-I didn't seem to work.

I even inspected the bottom of the main board.

To see if maybe there were some missing resisters or caps? (to maybe save on parts, because of the un pouplated ram pads)?

It looks like apple still placed caps there for all those empty pads anyways.

It's strange, because I really thought it would work, You know, just show 4mb ram instead of only 2. but no dice.
