Interesting.  Random thought.  I think with the second problem I know what you mean - sometimes my broken board (when it worked) would boot to gray screen and sometimes to HD (past…

I don' t think ADB is completely broken on these. The first one , non-corroded nice looking, was from a 3400c with a broken screen that i managed to boot with another screen before…

The picture above is of the old but still working 1990 70MB Quantum drive that came with the mac. I removed the A1 A2 jumpers on it and it indeed started loading System 7.5.5 inst…

Galgot - thank you very much!  I have to start working on my /200 board again; getting the solder off has proven pretty challenging.  I'm assuming none of those boards specifically…

Booting on a Mac takes time. I noticed that on my systems with a SSD, that there is a 20 second or so pause between the "Welcome to Mac" sign and the first extension loading. And s…

Yes I did it: I swapped the PMU board, but that didn't help. Wasted money! I tested with a known good PowerBook harddisk with system (and a CF-IDE adapter afterwards), disc…

Hi, I got the Kanga as non working: black screen, no start chime, but HD spinning a while (using known good power adapter). And: when I put in a PC formated empty disk, it's ejec…

MikeatOSX, what is the problem with  your Kanga?

Back again everyone, I received the new chip today and soldered it. Then I checked all the connections again just to be sure. First try using the new HDD I bought, it did the exa…

Define defective

I'm waiting for the next sequel. I have a defective Kanga.

Good luck with that. Make sure you get the same board. Buy a frame and put the old board on it and hang it up as art when you replace the board. Title it "My First IIgs."

Ok, swapped the ROM and it's the same. So the Mega II is the problem. Time to find another board. Thanks everyone for your help! Pitou!

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…
