CD-ROM Readers have a difficult time reading CD-RW Disks, but a CD-ROM Writers can read them easily if the support the CDRW+ format. Not all older CD Writers have CDRW+. If it does…

That I have not. I was wary since the loud pops the iMac could make scared me too much. I'm just a little too jumpy for that! :O I'll leave it on in the back of the office and tr…

did you let it sit on for a couple hours?

I gave the CRT, Analogue, and Power Board a good dusting, hooked it all up, and powered it back on. The screen still pops, though not as violently or loudly. This one is a head scr…

OK, I'll pay the extra US$30 to get the floppy module. My PowerBook 1400cs/166 has the CD module already in it. I'll also get a HDI-30 to 25-pin SCSI adaptor so I can Use SCSI D…

yup i sifted through the bull, and found this post, as trag mentioned they have got to it first. the issue looks most likely caps.   and it looks like they can (with this psu) be …

OVERVIEW A limited number of Macintosh II CPUs were manufactured with an HMMU-unique socket that does not allow the CPU to function properly if a PMMU upgrade is installed.  Custom…

I said that up top. Recalled because of a socket issue. The four chips to the lower right, see those? The black upper right one comes in versions that have different pin layouts un…

just an update havent had too much time to look into the power supply further.  But one thing, i did stumble across a site called atxg4.  He has adapters to use atx ps in g4's. He …

to uniserver, the board in the top pic is the one i am currently working on, its the working one.  On the other mac II i have the board pictured on the bottom.  One thing though, i…

If you can get both yes. I have a 2GB CF in a PCMCIA Adapter which I copied the System 7.6.1 on my 5300ce as a back up drive, and tried it on my 1400/133 & 166. They both …

Ya, but I am just making a list of models. Im not interested in motherboard variations, etc.

unity said: I could be wrong. I just have never seen a model like M0001EP or M0001AP, etc. I could put them into the list proper, but that would add a few lines for sure!  …

If it's just a dusting, that'll make things so much smoother. I disassembled it just in case I need to get to the analogue board. The entire enclosure was caked in heavy amounts of…

Should I purchase a floppy module as well as the CD module?

i found that if leave them on for a few hours, that noise stops.   seem they do that due to moisture and dust build up. if you can blast them out with the air compressor that woul…

YAY!

I have a 1400c/166 running 7.6.1. No problem.

So, I am thinking of getting a PowerBook 1400cs/166 off eBay to run Mac OS 7.5/7.6 (I'll probably use 7.6 since it's better on PPC) really fast. But, everymac.com says that the 16…

Here is the thread. It's still pending, the work is simple enough to do, but with his move, wthww has been pretty short on personal time and connectivity to make the fixes.

I don't know if they're prone like the early iMacs, but it's definitely an known issue. Probably needs an analog board recap.

So today a friend of mine came in with a big and beige PowerMac. It powers on and works, but the screen and picture tend to pop and go out. Are these models prone to flyback failur…

For the BIOS, the chip is on a support, and a colleague can help me to dump directly the content, i will try that next week.

General DTK question: has anybody looked at operating systems other than Mac OS X on them? Windows 7, 8.1U1 or 10TP would probably do really well on this thing, especially if the P…
