    Help restoring a newly acquired Lisa

    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...

    Software Request: PowerBook 3400c Mac OS 7.6.1 Restore CD-ROM

    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.

    Software Request: PowerBook 3400c Mac OS 7.6.1 Restore CD-ROM

    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...

    Quadra 650 Battery Bomb Repair

    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...

    Rescuing data from a Mac Portable HD on another Mac?

    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...

    Rescuing data from a Mac Portable HD on another Mac?

    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...

    Rescuing data from a Mac Portable HD on another Mac?

    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...

    Repairing PowerBook 140 standoffs

    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

    A tip about sound on the Performa / LC 575 (and similar systems)

    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...

    Workgroup Server 9150 Freezes Without Additional Cooling - Can anyone check their WGS VR temps?

    Hello all, I recently did a live stream (link) where I attempted to repair a client's WGS 9150. (120MHz). The symptoms were that the system would freeze after being on for a period of time. The voltage regulator behind the ROM slot had some visible singing of the board, so I decided to replace...

    Quadra 840AV - chimes ... kinda ...

    I don't think that would be the case? But my recapped 840AV seems to be perfectly happy with good quality (KMET, etc) tantalum capacitors. Have you tried the board without any drives or accessories plugged in? I know it's a long shot, but I think I hear the hard drive in your video clip. I'd...

    Quadra 840AV - chimes ... kinda ...

    I also echo the advice of Bruce, there must be a bad trace somewhere. At least that's my thought. The traces on those boards are silly thin and fragile. Also, because of this, I'd caution the use of an ultrasonic cleaner. You can use it, just be aware that in some rare cases it may damage weak...

    Mystery Apple KanjiTalk Font Card (NuBus) [630-0174-A] Does anyone recongize this?

    I tried but it won’t boot on the Mac II. I think it’s one version too old, judging by the Mac II’s original software version number (System Software bundle v2.0.1 - which includes System 4.1 / Finder 5.5) and release date of 1987. Also, that system disk doesn’t seem to have the “IIcard” or...

    Mystery Apple KanjiTalk Font Card (NuBus) [630-0174-A] Does anyone recongize this?

    Thanks to @fogWraith I spent some more time pulling my hair out about this. o_O I switched from my Mac IIx to my Mac II, as the Mac II can run pre-System 6 versions of the Mac OS. This seems to be what the KanjiCard wants installed. Sadly, whenever I have the KanjiTalk NuBus card installed...

    Mystery Apple KanjiTalk Font Card (NuBus) [630-0174-A] Does anyone recongize this?

    Thanks for the all the information everyone! 😄 It seems like I need the Japanese equivalent of Macintosh System Software 2.0.1 or 2.1 (or similar), this would contain System 4.1/4.x and Finder 5.5/5.x. These would likely have a date of around 1987/1988 to match the release of the Macintosh II...

    Mystery Apple KanjiTalk Font Card (NuBus) [630-0174-A] Does anyone recongize this?

    I've recently acquired this interesting Apple KanjiTalk Font NuBus card... and I'd love to learn more about what it does and it's purpose, etc. Doing some research, I've found other websites (example from okqubit.net) wondering what this is. I'm assuming it may have something to do with some...

    Mac N' Frost 🥶❄️💨

    I bought it because it was so funny! But @Adam really wanted it, so I gave it to him. I think he has it set up!

    Trenton Computer Festival

    Yep! Sadly (as seen in the photos I showed), the vendor area was a ghost town. Apparently they were charging $40 for the tables (although maybe that was for multiple?) Either way, I'm very much looking forward to VCF East this year!

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Well done!! The BlueSCSI 2 is shaping up to be an amazing release... if this infomercial (below) doesn't convince you to get one, I don't know what will. ;)
