Mac IIsi recap 1/2 Successful
Posted by: Elfen on 2015-06-12 12:32:14
Just finished a recap on the other Mac IIsi I have.

Almost there but not quite. Power supply turned on and clicked for a while. Eventually the PSU got it little's head straight and finally gave me a "Bong!"

Followed by the chimes of death.

I'm going to recheck the recapping job and see if anything is shorted out. But at the same time, this is an iffy PSU and the other PSU is dead as a door nail.

Mind you, before these two Mac IIsi's did not even turn on before. The PSU would click several times and then become quiet and that's it. Nothing, nada, DOA.

I have a lot of questions to get it going but first, I need to recover from a long day and radiation therapy I had this morning.

It giving the Death Chimes says it wants to work and that it's almost there...

Can the IIsi run without the onboard RAM?

Can the IIsi be powered (temporarily) by the IIcx/ci PSU?

-- so yes the psu needs a re cap

-- the IIsi does have traces that suffer that for the onboard ram.

-- yes it can, but you would need an onboard video card. i have seen some one ebay for cheap.

It won't fit in the IIsi case though.

LOL! I figured that much.

Just want it to let it hang to test the board.  :b&w:
