    PowerBook G3 Wallstreet/PDQ flaky power input jack

    ohhh, right. i mean, a dead PRAM battery in a wallstreet powerbook is kinda painful. the system will start for a moment and then shut off, then it will turn on after it takes its time to do the memory test of course. i would check your soldering joints of course, and perhaps clean up the jack...

    PowerBook G3 Wallstreet/PDQ flaky power input jack

    i think somewhere someone had a similar issue with the pdq's charging board and it was fixed by replacing a ceramic/mlcc capacitor: https://tvc-16.science/wallstreet-pram-replacement.html perhaps this might need a replacement

    Massive (filthy) find in South Carolina

    thats odd that they didnt have any HDI45 adapters, lmao. you'd expect to have at least a few with that many 6100s, given that no one really bought the audiovision monitors very much.

    MCL68+ A Motorola 68000 drop-in emulator

    i love fun projects like this where there's not much practical use, but it works. a lot of people generally dismiss the fun stuff... ugh! very nice work, would love to see it open sourced if possible.

    The Performa 5210 Disaster

    Nearly a couple months back, I won an auction on YAJP for a Macintosh Performa 5210 with a keyboard, mouse, and its original sofware discs it came with. Problem? With sendico, I had to use FedEx to ship it as I didn't have other viable options at the time, and I was told surface mail was not...

    Identifying and confirming fake 68040 CPUs (especially the L88M mask)

    I'm glad someone pointed this out. I was kinda skeptical about these eBay 40MHz chips... I sold a fellow member a genuine 33MHz 68040 not too long ago.

    Just a PSA...

    G5s have their batteries leak? Oh, I never knew that...

    eMac capacitors

    eMacs unfortunately do suffer from these quite often, and usually the through-hole ones are affected. I have never come across a unit with bad surface-mount caps. My first soldering job was a recap of a Macintosh Classic motherboard, in which I used a power dead eMac motherboard for surface...

    Help splicing a CRT VGA cable cut by ewaste [SOLVED]

    I hate when people cut cables off of nicer CRTs. Sure, it's a Packard Bell, but it's free. The evolution of technology has made it a little harder to find CRT monitors in some cases.

    They're better than what people think they are, and it would be a fun project! Sure, they may be somewhat failure prone but the first 3 models make great OS 9 machines. Certain models do need a patch, though. The 2005 eMac can be overclocked to 1.92GHz which makes it wicked fast, yet also...

    No problem. Never heard of such a mod, could it be doable on a Performa 475?

    Member bio - Nick (k24a1)

    Hello, I'm Nick, aka k24a1. I work on various computers and sell some whenever possible. I have taken an interest in PowerPC and 68k macs since the late 2010s, and did some projects on and off. I still work on these computers, and I have done research on some of them, especially the eMac. Some...
