polyfuses will open up permanently if the current flowing through far exceeds the maximum rating, itll blow the reed apart. 

Ha! So was I to some extent. People remember me as the first one in the 'hood to own a computer! But like you said, lets not hijack... So... TechKnight - I knew there was mention…

don't want to be hijacking this thread elfen. Sure the brother got me an SE from the place. I was the only one in my city, of my age with a mac (that I knew of).

I remember before 9/11 meeting a guy from that area who also worked for Apple, Falen. He commented how he loved the 5300ce (which I had out at Barnes & Noble Coffee Shop at…

and techknight doesn't even like computers

that is quite an interesting story!

Those are polyfuses. they are supposed to blow, and self-reset. 

This is great work! A much major improvement! Why was the scsi chip removed? There is a fuse (F2 and F3 right there!) that sometimes blows and makes your SCSI bus look dead. Chec…

Good Luck. Let us know what happened.

now your taking ozyman - good clean job - - onwards!

good job man!  

on a socket

If he hasn't got one, I know I do. My (Procrastination Plagued Project) Pile-o-1400s stretches approx 30" across the bottom of a bookshelf. The limiting factor is the Cracked Lid C…

I might want one!

I have a spare 1400 active matrix display assembly. I may even have two, I gotta check.

S short for STN, otherwise super twisted nematic.

Is the ROM on a socket or soldered in?

CTRL-RESET doesn't drop me into BASIC. It just restart over again (like a power on) Thanks very much for the explanation Gorgonops. I found a ROM replacement on ebay. I'm gonna tr…

Some times, you just got to say "Phucket! It works!" Now that you got it working, you can go back when you are up to it and replace the thick wires with thinner ones.

Oh dear gosh.....

WoW...that's one original soldering technique there! - ive done a bit of heavy jumping on boards, but I rekon you should take off all what you have done, clean the board a few ti…

Sure     I apologize for the unorthodox soldering as I realized only afterwards that I should have used smaller wires. But everything is connected.
