Hello Fellow Enthusiasts,
I was recently doing some work at a preschool when I came across a little gem in the front of the playground.
An Apple iie which had been used as a 'toy' in a childrens sandpit, despite looking obviously worn, damaged, grafiti and horribly weathered i asked if I could adopt the computer in which the teachers agreed on condition i do a demonstration to the children if/when it's repaired. So i began to take on this project - Silly Me.
Fun Facts about this machine -
It had survived a fire from 1989 in a highschool in which their was no damage taken to the machine but the School was destroyed and demolished, afterwhich this machine was provided to a primary school where it had lived out the rest of it's days until 1992. Which the machine was donated to this preschool/kindergarden in which it has sat outside in a sandpit/thrown around, used in games ect.
The Big Visual Problems:
- Rust - Lots and Lots of Rust on the bottom of the board and inside the power supply.
- The Case was very dirty and had drawings, scratches and one small break in the board.
- Missing keys - Mechanisms on most of the keyboard are damaged.
Just dirt upon dirt and at least half a bucket of sand. (NOT KIDDING)
After a clean in alcohol, a lot of scrubbing, grinding away rust, repraying the bottom of the board.
We were getting somewhere!
Now the part i was scared of: Actually Fixing it.
Power Supply: I replaced Fuses, Cleaned the Power Supply and overall just did everything i could think of.
But To no Avail: I built my own powersupply since the pin out was on the back of the computer. Simple.
So Now I have power to the board:
No PowerLight, No Beep no Display.
Reseated and recleaned all the teeth of the chips.
I Started Following a troubleshooting guide which was really useful but was designed for the NTSC board. Not mine. So That was No help.
Now Moving on - Does anyone have any advice or the following:
The Capictors list for the board as all of the markings have worn away and I'm not sure it's my multimeter or the capactiors but I can't get a consistent result. Plus given this computers history, i'd like to recap the whole board.
The Chip list for the board as once again the markings have worn away on some of the chips and I'm having trouble identifying some of the chips.
Please help me give new life to this computer!
