thinking and googleing about it, im going to take out the board and cover the acid damaged area with 3to1 baking soda mixture to kill any remaining acid.  let it soak into it for a…

well it says Ati 3d Rage II techknight........but from now on its the 20th anniversary UE8 by the looks of things

If thats the RAGE IC, thats why your video is scrambled.  those traces I pointed out, there are some opens.  You need to go over all of the traces that show "discoloration" wiht …

techknight - good call. Will have a look at them tomorrow. Just a continuity test between 2 via's on a single trace - will do - 0.1uf - that's great to know - will install new on…

have had no chime to date..........just strange sounds, clicks, noise, static...when floppy inserted noise matches the floppys activity - power/green light comes on sometimes, ot…

Hey falen:  Take a look at my photo. I circled areas that need tested for continuity checks. Especially the ones in the bottom corner coming from that IC.  Also the capacitor is …

With the battery pulled, I can get 2-10 seconds between the chime and the light coming on on my TAM. 

Question. You mentioned the light comes on. Do you get a startup chime? After pressing power, how long until it comes on? I just noticed that my light comes on but not right awa…

You dont have a 5500/6500 laying around do you?

Mine is the same brand. I think all the black boxed batteries in Macs are Rayovac. One cap maybe could. Until ruled out, hard to say if its the issue or now. You could try to trac…

Heres a few pictures people of the battery that leaked all over this TAM - I opened it up and you can clearly see the acid.... its all over the place. My fingers were covered wit…

hey unity - thanks for the helpful info. again I agree with all you say. Im thinking of removing c118, measuring its value, finding something similar , and as you said glue it in…

Okay, I will dig into it a bit. I emailed him. I certainly could have missed that model variation in my searches. With so many regulatory tags its hard to tell.

is that pad completely gone or is it just dirty? If it's just dirty then take a jeweler's flathead and scrape it shiny...

e-mail Eric Rasmussen on his site. There's nothing on that site he hasn't personally confirmed himself. From your initial list you are not accounting for the 240V Plus. This is it.

I am not well versed on checking stuff on boards, but if you need me to check anything else I am more than willing to do so.

C113 is indeed populated. Its ceramic, like others, so I can not say the value. Apple seems to stick to a common group though on boards.  So it may be like others such as C118. It …

cheers unity - appreciate it. I know nothing of the tam, its upgrades......I don't even know what cpu is in this thing. - ment to say...the pictures I posted above... the missing…

Some info on the ROM slot. http://appletam.ning.com/forum/topics/rom-slot-on-tam Also I will go check mine, C113 may not be populated. Also I wonder if a L2 cache is needed to b…

have to agree with you unity. When I began removing the caps there was plenty of electrolyte coming out of them. And after the full recap the machine was exactly the same it made …

I did quickly check your caps. Polarity seems good. I wish you had another board to test in it.

I can find no reason for that ROM to be in there. As far as I know, its not needed for the upgrade card. So keep it as basic as you can to see if you can get it going. By the way,…

hey unity. Why would that rom of been in it anyway. It will only show a display with one ram simm installed and nothing else. Will try the 2 rams but cant see it making any differe…

Do not install that ROM or upgrade processor card.
