that "thud" is the degaussing circuitry kicking in.
If that one isnt doing that, then look at the relay, degauss coil connector, and especially the thermistor and their solder jo…

Great accomplishments there!
Not sure about the magnetic interference. Faulty degausser, maybe?

Tonight is just getting better!
Stiff brush across all the IC legs and CC #2 which I got from the original owner around 12 years ago now boots up again complete with a health…

Had a small success just now in that I got one of my pair of non-functioning CC's to power on. After giving the various I/C pins a clean up on the IIvx board got that machine boot…

Although the "PizzaBox PowerToggle™" works, it's a bad idea if you plan on running the machine frequently, because what you're essentially doing is intentionally creating a power s…
From my experience the PowerMac 5500's had flyback issues also... basically it was just a matter of whether the logic board would last long enough for the flyback to fail. lol. So …

From what I have seen here vs. what I own, I've seen that there are about 3 Classic IIs. Mine - which has 4 ROMs in sockets (mine is a prototype of sorts as it ha…
Both Apple IIc's turn on, disk drive turns on and after a while shuts off - all normally as it should. Even the one with the RocketChip, even though the beep was normal. In some a…
When Dr. Levinson was alive, he wanted power for his Apple IIs, and got all the accelerators he could find including a TransWarp 8, Transwarp GS and RocketChip 10. There were also …
A good vacuum will take out fuzzy bunnies that smell like El Tobacco... but then washing out the case, boards and frame will be needed. Also the mouse and keyboard too.
Well, I do think the Retr0brite is a good idea for the case. Are you going to recap the board or send them off? If you're doing it, wash the logic board at least.
I've never had s…

I have found the IICI especially fussy, it as well as the IICX, IISI, IIVI, & IIVX use "Sync on Green." I believe declaring a 13/14" RGB monitor is what worked for me...
Here is my motherboard in my Apple II, I wasn't able to find the part number, maybe its under the keyboard part. My board has different slots, they have a little flange at the end …
Yes, you can swap that over no prob. I forget if I did, but I may have done the same from a IIx. With my 030 upgrade, it really did not matter in the end since I had to pull the ch…
@ unity, ok i took the board out and counted it, i have the 132 pins or a 13x13 row setup. I doubled checked and they are soldered through. One thing though, if this originally i…
