I always thought it had something to do with the VRAM. If you had too much VRAM you could not take the Mac down to black and white.
I think the cutoff was 2 MB. I remember that my…

If I wasn't going to install that fan, then i'd never have opened the case, and i'd never have adjusted the voltages. Simple....I somehow doubt i'll attempt the installation again.…
12v DC does not melt a fan.. you sure you did not bump the AC by accident?

I haven't a clue. Followed the guide to the word, it failed, and I yanked the powe…
Unfortunately the only reason I opened the case was to install a fan... and in the process of hooking up that fan I blew the fan and the fuses in quite a spectacular way.

I've been thinking about this for a little while now, and it seems to me that in my old Elementary school, there were candy iMacs that could go all the way down to Black & …
That anode cap is indeed a pain to remove. I usually use a small pair of pliers (from an eyeglass repair kit) to get the clip on one side pressed in and then use the pliers to remo…

Last night I opened my 512k to record all its capacitors (I think I've found a way around my worries about lead, so now I'll be ready to replace those capacitors!!! ).
But anyw…
Anyone heard of LUnix? Unix on a C64 - page seems a bit old though. And uCLinux ideas might be helpful about getting around lack of MMU.
EDIT: Doh...didn't remember that LUnix h…
At a minimum, the pinouts have to be remapped. The first 20 pins of the Disk II & Disk III seem to be identical in function, suggesting that the 6 remaining Disk III pins a…
I am pretty sure that the Disk ][ connects to a set of pins on the back of the ///.The blue port all the way on the left is where it would go.

Um, nope. That…

Well I made some adjustments, including as suggested to the voltage, and here are the results.

Bad geometry can either be caused by the power supply or by the little magnets on the neck of the CRT. Since those magnets are a pain to work with, I'd suggest a power supply repai…

I waited before I replied in case I was wrong, but I am pretty sure that the Disk ][ connects to a set of pins on the back of the ///.

There is a little bit of info on the Disk III and its use on a III+ here:

I recall reading a tutorial once about converting a Disk II to use directly on an Apple III, instead of buying the more expensive Disk III mechanism. But in recent Googling, I can …

Everything you describe sounds like voltage problems. Your Mac is out of whack. Get yourself a multimeter and go to work, starting with Dr. Lee's excellent notes. Then get yourself…

So this quest kind of died out this winter. I haven't really found too much more info, but I have an update. My 2400c lives again! My Mac OS 9 installation (or something :?: ) wa…

Yes, I fear that your TiBook has developed a problem with the BGA joints under the graphics chip. This problem is unfortunately widespread (the early iBooks were infamously prone t…

"Lonely Mac Syndrome" was a phrase I coined, tongue-in-cheek, to describe this machine's odd behavior (also in initial post).
Essentially, as long as I was working in a program, e…
