Hello everyone, As we all know, flex cables for a variety devices are starting to get a little bit creaky and in many cases have cracked. Great examples of these are display cables for the Macintosh Backlit Portable, PowerBooks, and the eMate 300 (though in the eMate's case it's because of a...

I had no idea that little power supplies like these even existed. It's under-rated on the 5v line by a bit, but so is my board. And this is all-in-one. Just needs cabling and mounts.

The 5v regulator is rated at 4.25 amps, slightly less than the 4.75 which the original power supply is rated for. It can briefly push 6 amps (this is the peak current limit), and if a small/quiet fan is integrated then 4.75 amps is probably doable. Just needs a fuse rated that high, currently...

Been a long time since any updates, sorry. I'm sending a pcb and parts to @GeekyBit so he can put together a better mounting bracket than I designed. The PCB accepts a 12v power supply with barrel jack, or direct wiring into a 12v supply. There's no switch on the PCB, so your external 12v...

Yes, the push and twist method is my favorite for removing the little SMD can capacitors. Never ripped a pad.

Feel free to ping me with whatever questions you have

SCSI only "needs" 19 pins. 18 for data and control lines, plus termination power. The 50 pin scsi connector is mostly ground lines. The 40 pin powerbook scsi connector has three power sources: motor power, drive logic power, and termination power. That's 5 pins used, leaving 34 (one pin...

My attempts to increase the RAM and Flash sizing look like they aren't going to work out. Fortunately, my efforts have resulted in a working module with the same capacity as the original! Fork of Stephen's repo is here: https://github.com/androda/eMate-Expansion The CL-PS7010 RAM and Flash...

Maybe a Mac with question marks as eyes?

My questions are primarily around site management. Is there an information page showing who all the admins / staff / site officials are? Is there an upper limit planned on the number of site officials? Is there a process for 'demoting' site officials for misbehavior or other issues? How were...

What do we think should go under Resources then? If nothing seems to fit, can we disable that header to avoid people getting confused?

In the dark theme, it's quite hard to tell which threads you haven't read. The top one in this picture is unread. Would be easier to see if highlighted with blue dots, like on the overall forum view.

@Kai Robinson or @eric could we get some resource categories (more than'example category') ? Do my suggestions (see first post on the thread) make any sense?

Unfortunately it's not quite that simple. The LC PSU is 0.75 amps at 12 volts and 3.75 amps at 5 volts (with a tiny -5v supply for Serial or someting). Not really a lot of power going on here. IIci and similar have more along the lines of 12 amps output at 5 volts. Q900 has something absurd...

OS version is not likely to make a difference. This sounds like a hardware problem, the Ethernet port has a bad connection like you mention or maybe something's wrong with the driver chipset.

There was a project doing exactly that called the mAcTX LC. They released the PCB design as 'public domain' back before the latest 68kMLA data loss incident. I didn't like that approach (PCB design junkie) and went through the process of making my own. The MACAA will be compatible with...

I'm working on something along these lines, called the 'MACAA'. Uses an off the shelf MeanWell 12V power supply plus custom 5v and -5v converter board. These plus 3d printed mounting solution and either reuse the old connector or newly made connector (because the shell and contacts are still...

Here you go, this is the design I came up with for converting internal 50 pin SCSI to something a 2.5 inch powerbook drive can plug into. https://github.com/androda/PCBDesigns/tree/main/Adapters/50PinInternalSCSI_ToPB

Thinking out loud here, but under the Resources section there's only 'example category' currently. Would these make sense as resource categories? * Capacitor Guides (for images with location and value of capacitors on boards) * Teardown Images * Schematic PDFs * Software It's quite nice having...

@eric The links to capacitors C201 and C302 don't seem to be working. There appears to be a tinkerdifferent URL prefix (before the actual mouser link) which is likely the culprit. And I'm pretty sure C201 is 1200uF, not 12000. :)
