nonworking apple IIe *Help!!
i recently aquired a apple IIe... had been sitting in a barn for who knows how long. it had years of grime all over it... keyboard was literally almost unrecognizable. i completley dissasembled it, washed the case in the dishwasher (much to the mothers dismay lol), cleaned the motherboard and psu, as well as the monochrome monitor. i then went to try and boot it up.
Well, at first i thought i had a brick. the system beeped, the moniter displayed random garbled ascii, and then the speaker started making white noise...... Finally realised i didnt have the keyboard plugged in(dont know why this would make a diffrence but whatever). So i plugged that in, and rebooted.
Well this time the system made its happy beep and the screen displayed the typical "apple ][" at the top. then... nothing. no keys worked, no speaker noise, just nothing. after a couple boots like this, i manageed to pound the keys in some random unknown combination and the machine went to basic... sort of. i was able to press pretty much all the keys, and they all seemed to be working (except p, which reqired several hundred key presses till it worked haha). The only problem is no code ever worked... always syntax error. syntax error..... nothing else. so i rebooted sevral times, finaly managing to hit some random keys bringing me to basic. Still nothing but syntax error.
Well at thistime i decided to try reseating all roms. so i tooke them out, doused them in contact cleaner, and put them back in (one by one btw). and now, lo and behold, were back to garbled text on the screen... and not even a beep.
I am a newbie to this (this is my first restore project). So my question is, is this even fixable? i really dont have access to things like olliscopes or any thing. is there any way i can voltage test the chips or something?
Oh one other thing... the motherboard is pretty much in excellent condition, but on the underside, some of the traces or whatever are sort of wrinkled... Not broken through just wrinked .Im pretty sure its moisture causing rust. is a mobo in this condition good to use?
