    PowerMacintosh 7200 - Looking for Stability Suggestions

    I tested a locally gotten 7200 for a few weeks before passing it on to CoryW. Seemed fine—no issues in day to day operation I noticed. I did use it extensively on a Power Computing PowerTower, which is Catalyst architecture derived (even down to its particular memory type requirements), for...

    PowerMacintosh 7200 - Looking for Stability Suggestions

    FWIW I've had the best luck running 7.6.1 on pre-G3 Power Macs. From System7Today's list of "ultimate updates" I pick and choose https://system7today.com/sys76-on-powerpc Definites: OT 1.3 AppleShare 3.8.3 2020 patch (OFC) Optionals: LibMoto Text Encoding Converter 1.5 SpeedDoubler (but it...

    JLCPCB seems too good to be true

    The MO of the youtubist. Full disclosure I haven't watched this particular person's content, but it seems to be the modus among the "cool" kid crowd. I'm on the scale of "boring host has better content" (generally). I've heard some suggest JLC has state subsidized production, which seems to be...

    DayStar PowerCache 50MHz IIci Performance Results

    Bears repeating: if you use Bolle's SE/30 adapter, all versions of the PowerCache should work. The TwinSpark adapters will only accept Universal.

    Mr Fahrenheit’s conquests

    Yeah! INL! I still haven't been to Monument Valley… in fact I've only been to two of the five national parks we have. It's way out of the way, but I highly recommend Goblin Valley state park, as well as little wild horse, since they're right nearby. Great hikes that aren't too demanding and...

    Power Computing 60MHz Bus Capable Models

    Hm. I was skeptical at first, but I've come out of hibernation to dig about the issue. Here's an internal PowerComputing doc: https://cdn.preterhuman.net/texts/computing/PowerComputing_manuals/PowerSpecificationSheet.pdf So the MacGurus chart seems more accurate compared with this PCC...

    MICRON Xceed Grey Scale video card with the works for sale on Buyee! I wonder how much this one will go for?

    there's a breakout board with a ribbon cable that connects to the bracket on the back of the SE/30. that's where the RJ45 / AUI is.

    IIsi Dual PDS Riser

    That's the one! :)

    IIsi Dual PDS Riser

    I have this exact card in a box somewhere. It's a pin-thru PDS riser and FPU socket—no frills, no special anything. PDS video cards meant for the IIsi aren't common from the NuBus Era, so 'grats on getting one of them with it. MUCH better than the vampiric on-board video. Definitely look for...

    Help with performa 6300cd

    I'm not even sure what "era" to call it (or if it even can be categorized like that), but at a certain point, most PowerPC Macs started to have multi-sync on-board video hardware, and will output all VGA+ standards and refresh rates. I want to say all post-x100 PowerMacs, but I can't speak to...

    Help upgrading a Performa 600

    Is the seller saying the HDD is getting warm? That's what I'm gathering, but correct me if I'm wrong. Spinning SCSI HDDs from this era—regardless of what some might say under the influence of nostalgia—are either bad, or will go bad. A solid state replacement is a small investment in terms of...

    Quadra 700 Repair - Screwdriver Heatsink Removal Whoops!

    As far as thermal paste… don't use the expensive stuff. My Centrises (Centrii?) and Quadra boards had the white paste on them, and since the ceramic substrate doesn't conduct as fast as modern metal lids do, an expensive, thermally efficient paste IMO isn't necessary. Additionally, while I've...

    Quadra 700 Repair - Screwdriver Heatsink Removal Whoops!

    Prying off the heatsink, at least the way a lot of examples show, is …unwise, as you've unfortunately found out. The "safest" way I've found ends up bending the heatsink fins (furthest from the actual CPU die, mind), but it's a small price to pay— you place a tool on the inner side of the clip...

    A 'once and for all' declaration regarding L88M mask MC68040 CPUs

    Thank you! I knew I was missing something. I trust them more than UTSource—a recommendation from me, as well. He even sent me another MC68040LRC40 when one from my order was a dud.

    A 'once and for all' declaration regarding L88M mask MC68040 CPUs

    Okay, here's something weird I'm trying to understand: so the V versions can do either 3.3V or 5V? I was told they could only do 3.3V, which is why people weren't using them. Sorry if I've been parroting more anecdotal BS by saying they can't. Or maybe I'm reading that wrong, but the verbiage...

    A 'once and for all' declaration regarding L88M mask MC68040 CPUs

    I need to self-crit on this. I'm making strides to move beyond my weird obsessions. I honestly, now, couldn't care less :) I've apologized privately to the individual I went full passive-agressive on regarding the issue (which is/was my issue), and I don't want to let something that is made up...

    A 'once and for all' declaration regarding L88M mask MC68040 CPUs

    This… Also the shipping times are so extreme sometimes that you'll miss the feedback window (and sometimes the return window). Not talking about that seller specifically, just in general.

    Classic CRT to SE/30 ?

    Note here: early built Classic I CRTs are plug-and-play with the SE & SE/30. At some point during their run, they converted the yoke wiring over to what was seen on the Classic II https://68kmla.org/bb/index.php?threads/the-compact-mac-crt-guide.8543/ All the same, I took a similar gamble on a...
