Hello all, As someone who repairs a lot of systems, the CUDA / EGRET microcontroller chip is one of those pieces that is getting harder and harder to replace. It would be amazing if these chips could be replaced by a modern solution so we can save more 68k / PowerPC Macs! I was doing some...

I've contributed to the WiFi DaynaPORT wiki in an attempt to make the set up process a bit smoother for you eager beta testers. It now covers some basic steps for both MacTCP and Open Transport methods. It's very exciting to see everyone testing this out... that WiFi desk accessory is soooo...

Great new beta feature! 🎉 I've tested this on my Mac LC III (7.5) and Centris 650 (7.6). I can even install Open Transport 1.3 and the AppleShare client update to connect to my Mac Mini G4 over the network! Granted, at this stage this is really only usable for web browsing, BBS, email, etc...

Yes! The issue was four of the RAM modules were not playing happy with the system. I also had to figure out how the device worked. When it gets power, the "Ready" light blinks once or twice. If that light turns off and the "Access" light blinks 4 times, then there is an issue with the modules...

Hello, I'm looking for a driver or software package that shipped with the Newer Technology SCSI Dart, a RAM disk drive. Any leads would be great! I've checked the usual places, but nothing so far. It is also possible it could carry an odd name. Thanks, -Steven

That's awesome you were able to speak to them. If you have their contact info, please send it in a DM. I'd love to ask them some questions :-)

Yes! I remember getting this book in the early 2000's and being confused that those images were missing. Thankfully at the time the website was still up (and now it's archived). I remember trying to reach out to the author once, but I don't recall every hearing back. I'm glad this wonderful...

Thanks Kai! :love: Q2 gives me -11.8 V on the middle pin and -5 V on the right pin. This is appears to be the same on the working IIci. I will however check on everything else you suggested too, thanks! Update: Swapping the RTC didn't change anything. Swapping the ADB chip didn't change much...

The only chip that got hot (126 F) was UC4 (behind the serial ports). And seeing as the other working IIci is happy without it, I removed it from the problematic system. However that didn’t seem to make much of a change. It seems the color / pattern I see when pressing the reset button changed...

Hello all, I'm working on a particularly unhappy Macintosh IIci board. After a recap and repair of the startup circuit area, the system turns on (with a green LED on the board), but I don't get a chime. The speaker does "pop". I'm using known-good RAM and the PSU is good as well. When I turn...

This is part of the design of the Lisa system. I believe a relay simply cuts off the power, thus the not so graceful shutdown. Every Lisa I've seen has done this. It is a bit jarring, but that's how it was designed.

Nice Lisa! The Widget drives are notorious for being problematic, but they can be brought back to life (with some success). There are Lisa HD emulators (project info here), and this individual sells them. FYI the recap guide I have for the Lisa 2/10 is the model with the 1.8 Amp power supply...

The manual for the PowerBook 3400 specifically says booting the system holding Command + C. If that fails, plug in an ADB keyboard and try it on that.

When trying the disc image from Macintosh Garden (link) "PowerBook3400CD.ZIP", it tries to boot when copied to a BlueSCSI v2 (and simply renamed "CD1 PB3400.iso") on my Power Mac 8600. Of course it freezes because the CD doesn't support that system. However, based on that, I'd assume the disc...

Great work @Elemenoh ! You in turn inspired me to take a look at mine again. My 650 had a nasty battery go off in it too. On a previous stream I repaired the traces, but it was not fixed. So double-checked all the traces near U60 and the RAM chips and they all seemed to be repaired. However...

I found my Conner drive from my LC II, it's a Conner CP3040A, the board looks quite similar to the Portable's too, except for the bigger SCSI port and termination blocks. I swapped over the board and the magnet (as the Portable's was quite worn) to the Portable HD and plugged it in. When the...

I'll try SCSI Probe, I had the wrong version of it on the disk and it wouldn't work on System 7.1 / 68k machines. Mt. Everything is very similar to SCSI Probe, but I'll try that and SCSI Director 4. Update: SCSI Probe 3.x and 4.x show the devices in the list, but I can't select them or select...

Hello there, My partner in crime @Action Retro brought over his Mac Portable, the SCSI bus wasn't happy on the unit, but we wanted to see if the HD had any data on it. Thankfully his portable would boot from a floppy. I now have the Portable's hard drive here and a 34-pin to 50-pin adapter...

Which stand offs are you referring to? The ones that hold the LCD? The ones under the keyboard? For example, some models exist and we could help if we had more info. Maybe upload some photos? This standoff is for the LCD screen / hinge area: https://www.thingiverse.com/thing:4818669

I wanted to share a quick tip about the sound chip on the Performa / LC 575 and similar Macs. We all know that leaking caps can kill these sound chips. Of course this could also eat away traces on the board and make the sound only partially work. I had an interesting scenario with a client's...
