It is, most devices these days are RISC. They're just not POWER.

There is no ROM SIMM for the TAM, never was unless proto. Good theory on the ROM with startup chime. I can not say, but falen5 I think has the skills to swap ROM chips if needed.

I was having the same problem as you... see my thread below.  I had to wash the board 5 different times to get it to work.  I also discovered pin 50 bent, touching pin 49 on the c…

It WILL work without that ROM SIMM for sure.

Also, just as a minor point on the chemistry, if vinegar neutralizes it, then its an alkaline substances eating the board, not an acid, you can't neutralize an acid with an acid (a…

Focus on that rom slot and it might work, you might not even need that rom since the 6500 doesn't but I'm not sure...

gave it a good wash - vinegar/water 50/50, then the usual water and washing up liquid it looks allot better - there is still some green , but allot of the via's that were all gr…

I looked and from what I can see the 6500 board would only need slight modifications, The scsi port is removed and the audio ports are removed and replaced with the small board on …

It is but it has some special pieces for the sound connectors that the 5400/6400 board(s) don't have. 

Yeah; anything from the G3 Snow and Dual USB have the smaller PowerBook PSU Connector. Lets hope for the best here.

I'm pretty sure that it's a 5500/6500 Logic board

thanks haplain - will do the vinegar.........jasus im gonna stink!!

Hello, I'm not sure able acetone. I do know that vinegar will neutralize the acid but not entirely sure about acetone. I would do vinegar and water mixture (50/50) then rinse with…

thanks for the reply haplain. - im going to clean the whole board then recap it. - I read somewhere that when you wash  the board in acetone in stops any futher decay from the …

The card with the heat sink is a Sonnet 400Mhz accelerator. They are quite rare. They came in 300/400/500Mhz. The 500's are really tough to find.  I would clean that ROM slot but …

just had a good look at the main board with my magnifying glass - on the back of the board there is corrosion but I don't see any compoinents missing. Will have to go very very eas…

got it apart lads. - found a great guide online - heres what the bones of this tam looks like - its not good!!! - see the green INSIDE the rom slot -aaarrggghhhhh!!!! - aga…
