Mac II

Initial state (as acquired):

Something was rattling inside - turned out to be just one of the floppy slot blanks - now returned to its proper location

Does not power up from either the keyboard or the power switch

Does not appear to have leaky caps

Original factory batteries - not leaked

Original 40MB HDD - 5.25" half height Quantum

-------

Chimes when 3.6v applied to PSU sense line

Appears to be booting from its HDD

No video - tested the Toby card in my 7100, no output either. techfury90 on IRC mentioned that it could be an issue with the DB15-VGA dongle, but I don't have an Apple monitor to test it with.

Still a Sad Mac xx(

A little history...

Insidious creatures just biding their time to set up my logic board up the bomb, and send it on its way to destruction...

What's this? Seems to be a beverage cup warmer that doubles as a data-storage device!

Performa 6400

Initial state:

Boots with chime but no video, every other time

Original HDD - bad - click o' death

Original FDD - appeared to be bad (no motor activity whatsoever on insertion of disk, but see below)

Sonnet Crescendo G3/300 in cache slot - removed (what's the point of putting a G3 in everything?)

ixMicro TwinTurbo 128 M2

-------

Battery puke on mobo - refer to pics

Lots of blue deposit - looks like copper precipitate to me

Did some casual (read: I'm lazy!) swabbing with isopropyl alcohol on the bigger spots of deposits - it now boots every time and the floppy is also working perfectly! (Will do a more through rinse on the affected area of the board at a later date)

Is now a Happy Mac :)
