    SE/30 PDS issues

    How are you running the Carrera without the Wish I Were extension? I finally got my Carrera to work today after months of fighting with it. Do you have a useful custom ROM that takes care of that or something?

    PPC740L G3 CPU Daughterboard For Blackbird Powerbooks

    This thread is fascinating. Didn't realize it got updated in 2024. I have the NewerTech 603e 183 MHz card, and am interested in what's going on here.

    LC 575 Comm Slot Ethernet + IIe Card

    I have the Apple version of this Ethernet card, and I'm also very curious about this. Many people say that they won't work together, but is that because of the 24/32 bit conundrum? We all know that the Apple IIe card "says" it needs 24 bit addressing turned on in order to function, but then...

    "Power Macintosh Card" and "601 Processor Upgrade" - What is the difference?

    Following up on this: I have two of these cards, one has bent/broken pins on the 040, and the other one gives me no video when switching from 040 to 601 boot. Will always show desktop when booting to 040.

    Mac 512k memory expansion question

    Apparently, if you hold down the mouse button while booting, it will bypass the ram expansion and just show you what’s on the logic board directly. I’ll try that and see what happens.

    Mac 512k memory expansion question

    The photo I sent with all the chips, you can see the JP1, my cleanup job wasn’t perfect, but it says 2048 now so I’m happy about it. When I was inserting the ram chips, I got a sad mac code. After removing the board I noticed that some of the chips legs were outside their sockets!! I fixed...

    Mac 512k memory expansion question

    Yes, that photo showed what it looked like before I removed it. I think you’re right about the 512k on the logic board. Hard to find an original 128 I guess as most users seemed to upgrade theirs.

    Mac 512k memory expansion question

    When I first installed it, it said 1024, which I think is the motherboard ram as well as the first row of chips. After I removed the solder bridge, it doubled to 2048, which was super cool. I wonder if that means the 128 had been upgraded to 512? It’s hard to tell because you’d have to remove...

    Mac 512k memory expansion question

    Here’s some photos. That JP1 needs to be clean (remove the solder bridge and then it sees all chips, not just the first bank.

    Mac 512k memory expansion question

    Circling back to this: we recently picked up a bunch of Mac stuff including a 128k with the Macs-A-Million ram expansion. I bought 50 41256 - 10 chips and fully populated the card. Booted up MacDraw to see how much RAM showed up. It only registered 1024 KB. Then I found this thread and...

    Macintosh 128K Week 9

    Nice find! We recently picked up some older compacts and also noticed that some analog boards had that aluminum shield. Interesting. My 128k has a Macs-A-Million ram expansion, but it’s only partially populated. I have replacement chips for it though to fully populate it.

    Digidesign NuBus expansion box

    I used to run Digi chassis on PowerMac 7100/80. Had the newertech G3/300 card installed in it as well. I have many PT installer CDs, but I don’t know if I have any authorization floppies. I do have some Sound Designer II floppies somewhere.

    Interware Booster CV 40 - Doesn't work on SE/30

    Just circling back to this, will the Turbo 601 card work with Bolle’s riser card in a IIsi?

    Mac Color Classic analog board crackles/whines/sizzles/hisses w/ video

    I had this EXACT SAME SOUND on my Color Classic analog board. Just a caveat, we had done the 640X480 VGA mod to optimize using a 575 Mystic upgrade. It was coming from the yellow transformer area. When the machine was making that noise, the screen would have lines on it and be kind of wavy...
