    Why is my Mac sad?

    I have tons of ZIP drives! Parallel and SCSI external, I've got an internal SCSI one, and I have several ZIP100 and ZIP250 ATAPI internal drives as well. Almost all work! Just don't have any way to connect the external SCSI drive to my PowerBook G3 because the SCSI connector is HDI-30 and the...

    Just ordered a Quadra 950, any known caveats or advice?

    I went on a road trip recently to go get mine. $300 from a member of another forum, and I bought some other goodies for it as well. Shipping is insane on these machines. System works fine, but came with no keyboard/mouse/cables and the side panel is slightly broken. Front is pretty yellowed but...

    Why is my Mac sad?

    I thought that the patched software might fix the "Unsupported" devices, but it seems strange that several of the unsupported disks actually came out of other Apple products. The Miniscribe 8425S I tried even had an active, working install of Macintosh System 7.1 on it for my Macintosh SE, and...

    Why is my Mac sad?

    Oh, and curiously, it seems like more "Modern" Macintoshes, even just later 68k Macs, really do not like older SCSI drives. I have a large collection of mechanical disks, but few are SCSI. The Quadra 950 being discussed, a Performa 631CD, and a Centris 610 were all totally unable to access...

    Why is my Mac sad?

    Alright, I've got it figured out. Hopefully this will help someone else out there so I will write my steps down. The disk is not dead! Attached to an IBM compatible, it's fine but shows up as unformatted. Disk formats with no new bad sectors on the PC side too. It was attached to an Adaptec...

    Why is my Mac sad?

    Well it gets to the desktop now, but I can't get any further than that. Any thoughts? Cursor still moves but nothing does anything, it's totally deadlocked past that once it gets to desktop.

    Why is my Mac sad?

    I don't particularly like solid state solutions, especially in vintage machines. I'll probably just finally get to backing up that Seagate drive's contents and re-use it in this machine.

    Why is my Mac sad?

    Shift key was the first thing I tried. Absolutely nothing, just goes straight to sad mac at first disk access. I burned a disc with Mac OS 8.1, holding "C" on boot brings me a sad mac with 0000 000F 0000 0001. Turned out the optical drive was not terminated properly. Wonder why it worked in Mac...

    MicroMac Power Workstation

    Absolutely beautiful! I was actually reading about this setup on their website the other day, MicroMac really made some crazy contraptions. Do you have any of their SIMM converters or memory splitters?

    What should i do with this Macintosh ELSIE prototype ?

    Would be nice to get ROM dumps before they inevitably lose their contents. Would be much easier to determine differences that way as well.

    Why is my Mac sad?

    Hello all. I just got back from a long road trip (~950 miles) purchasing a Macintosh Quadra 950 and several spare parts and other machines from a gentleman with the usernam 360alaska. The main machine I went to pick up was the 950. Machine worked before we left, worked when we got there...

    Just ordered a Quadra 950, any known caveats or advice?

    Fans in the PSU are notoriously noisy and the key switch is of very poor quality. Be careful with the switch and I highly recommend replacing the fan. Cable routing in these blows. Careful of the plastic tabs on the cover as with any vintage Mac. These machines support NuBus standby power...

    Quadra 950 CD Audio Cable?

    Yes the connector between the RAM slots is for CD audio input. With no cable, there should be two jumpers installed grounding the input to reduce noise. Remove the jumpers and any 1x4 pin connector with 1mm spacing should fit it. It's the same metal pins and electrical layout as any other CD...

    I killed my Quadra 950 - kind of!

    I believe Mac OS internally treats both SCSI controllers as a single bus - Despite two SCSI busses, for Mac OS to work every device on BOTH busses must have unique IDs. You cannot have a device #5 on both busses, despite the physical hardware supporting this. I think A/UX does not have this...

    Quadra PDS connector source?

    The same connector is used on Quadra 950 and WGS 95 if that helps you any. I believe the same physical part is used for the PDS riser on Centris/Quadra 600,610 but is not electrically compatible. If you do wind up making a cache card or other accelerator for these machines I would be very...

    2022 PowerPC Challenge!

    If that turns out to be the case maybe I will have to start looking for a Radius VideoVision Studio and do the editing for my YouTube channel on the 68k machine too, just to show off! This is a fun challenge. I don't think I've seen anything like it in the DOS/Windows community, nobody really...

    2022 PowerPC Challenge!

    Modern day isn't a big deal for me. Microsoft Word and Excel both work just fine, almost no different from their modern counterparts for almost all usage. Netscape will happily render my own website while I edit it, and it's not awful at playing music in the background while I work. It struggles...

    2022 PowerPC Challenge!

    In terms of usefulness, I do own a PowerMac G5 dual 2.0 that I saved from the crusher several years ago, and a PowerBook G3 Kanga. Oh, and a couple iMac G3 trays. I would not consider the Kanga a "useful" machine, although it is very entertaining, same as the iMacs. The G5 despite working is in...

    2022 PowerPC Challenge!

    I suppose that makes sense. To me, the "spirit" of the challenge was in doing daily tasks on outdated machines, but if the focus is more on PowerPC I don't really have anything interesting to enter, sadly. Maybe I'll track down a Daystar board for my Quadra 700 that won't cost double what I...

    2022 PowerPC Challenge!

    I'm new to the forum, but not to vintage Macs. Asking out of curiosity, is this event planned to happen next year as well? I would love to participate. Does anyone know if 68k Macs are allowed or will be allowed, or do I need to track down an unobtanium upgrade card to participate properly.
