Just as a useless note, SheepShaver will let you go down to 16/4 colors and B&W. On a PPC machine it runs using native CPU, thus it's potentially a more useful option then …

My Clamshell iBook BlueBerry can go down to 256greys only. Its runnning OS 9.

I hope that doesn't mean you don't plan on opening the case again. Aside from the fan, your analogue board is showing signs of age, despite adjusting your voltages the Mac is exhib…

I remember a lot of old games used to come with both B&W and Colour binaries, and on Power Macintoshes you would often have to run the B&W version in order not to g…

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.…

Are you sure? I don't think I've ever seen any PCI based Mac that could go down to 16 colors or B&W. The lowest you can go is 256 greys.

12v DC does not melt a fan.. you sure you did not bump the AC by accident? Click to expand... 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. Click …

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…

Well I made some adjustments, including as suggested to the voltage, and here are the results. 1. When powering up the Mac from a Cold Start (such as turning it on after being …

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…

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…

2. The raster seems to be a little out of whack. I'm assuming the CRT itself needs adjustment, Click to expand... It could even be the power supply.

These issues aren't so major, but i'm after some ideas as to why they may be occuring. 1. When powering up the Mac from a Cold Start (such as turning it on after being switched of…

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…
