Oh GOD no... that reminds me of the light seals in vintage film cameras (my other collecting hobby :) )... they tend to turn from foam into some kind of VERY nasty black gunk... one touch with your finger and you ruin the whole seal...
no i have one, but only one. so i cant test it with a pass trough terminator between the plus and the disk and then ANOTHER terminator on the end of the chain.
Thats correct, i'm in Holland :)
Yes i will take more pictures of it today. I'm actually already using it for a school project. I'm with the Design Academy located in Eindhoven, The Netherlands.
The goal of this assignment was meeting a stranger. so i did, and i want to show my class (mostly...
first of all... i dont really know what the proper way to display images in this forum is, so i'm going to upload them to an external hosting site to be safe.
I just got me a Macintosh ED!
It's one of those scary Educational machines... basically just a 512Ke with a plus front bezel and a...
Allright, just 'discharged' the CRT... there was actually nothing to discharge. I did the 'yank the cord' method first, then opened it up and tried the official method using a wire clip and a long insulated screwdriver. no spark, no pop, nothing :) properly discharged it seems.
now lets re...
James or any other person who can answer this:
Where does the HV on the anode cap come from? Is this mainly the flyback transformer -and thus are the pins on the flyback containing any of this high voltage or not?
i'm willing to try to discharge the CRT when i have a proper insulated long...
okay so a weird thing just happened:
Had my classic boot form the internal HDD, with the syquest drive attached to the scsi port, the bottom port on the exclosure having a terminator.
Took the guts to load a copy of Lido just to see what it would do... Chose the easy setup and chose a disk...
Guys, it turned out there was a hidden backup of the system folder far away in the folders that was being seen as THE system folder... removing the system file from it made me able to bless the main system folder.
Problem solved :)
if this video IS real... it would mean that the macintosh indeed did have a larger format disk system in its early prototyping days

judging by the cut out hole in the upper right corner of the disk icon it is indeed a twiggy disk... so there must have...
also found out about the caps... mine had a lead that broke off the print... did however not make any difference sadly :C
btw Techknight, thanks for the video about the temporary fix by manually moving the heads! helped me get data off a drive without any issue.
Okay... some bad news.
Replaced the both caps with new ones.
reassembled everything... it does the same thing... doesnt boot... everything spins, no video, no bong.
Found the diagnostic leds on the logic board... guess what:
Led 3 - indicating good video communication - comes on for just a...
Thanks for the suggestion! Successfully fixed 3 classic mac boards using that recap method, was not sure if that method was also appropriate for the bigger sized non-smt caps.
When i got the mac i went to pick it up from his home office. I was surprised to see another iSight 20 inch standing...
You were JUST ahead of me :)
i wanted to ask how bad i would get killed here for trying to cut the cap with paper around it to catch up any electrolyte and soldering the new caps to the existing leads...
That seems like an o-k idea?
Took the guts and completely teared it apart without even breaking the metal tabs on the front bezel.
took out the psu, nothing looked blown or burnt, no burn marks in the case whatsoever.
Took out the logic boards and removed both of the heat sinks. Found two cases of dry cooling paste and...
