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

    All the tests were with no heatsink at all. This is not aimed at you, but you bring up a good point: The myth-to-be-busted "cool to the touch", by implication is "it doesn't need a heatsink." If "cool to the touch" was intended to be applied to a thermal-managed CPU, it would be a moot point...

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

    I simply don't want the thread to derail. I want to keep this, as much as possible, about the thermal properties and debunking the bull$#!@ claims that have been parroted since time immem—no maybe the last 20-25 years or whatever the window is. There is a dedicated thread to fake chip ID, well...

    Is it easy to replace a Quadra 650's PSU?

    I'm one of those few who doesn't mind re-capping a PSU, tbh. Unless you've got a rectifier issue, then it's new PSU time.

    Jessenator's conquests

    I just realized I took photos of the module and didn't post them :| So here they are! This was one of two that I've seen …ever, and that second one wasn't even in person. This, the scond one isn't mine, but is a different design, which is interesting: There's at least a third one, which...

    Okay, this one is evil genius

    wonderful! I had thought (keyword: "thought") about doing something like this, and MAJOR kudos to you for seeing it through.

    Jessenator's conquests

    After a happenstantial exchange with @treellama on IRC I agreed to purchase a 4MB SGRAM module for the LPX-40/Tanzania/4400/StarMax etc etc motherboard, and it arrived in good time! Booted right up in my StarMax 5000. It allows the onboard Rage II+ DVD chipset to support 24-bit color at up to...

    unknown 'fat'-chipped module?

    the PCI Power Mac series had one kind of connector which is the topmost specimen in your image, the x400/x500 (and the 6360) had a different pin arrangement in their connector: And ISTR that the NuBus Power Macs also did, which might be the specimen at the bottom in your photo. Unless it's...

    Can’t get PM7220 to boot

    They're fairly generic copies of (probably) an original, but there isn't much to them, besides some voltage regulation it looks like. I know this is a US listing, but this is the one I bought. https://www.ebay.com/itm/111977195791 I also got a PCI slot-insert model which is handy: not the...

    Can’t get PM7220 to boot

    Interesting. I've never used IDE -> SD card devices before. But if you've got it, and it was free, sure! Tell us how it works for you. I picked CF since nearly all of them are passive / pin adapters, and I had spare CF cards laying around. Use what you have on hand when you can, I say ;)

    Can’t get PM7220 to boot

    Like I say, your mileage may vary. It's worked for me, where a max burn speed hasn't, and that's as far as I can take it, sadly. It's not something I can empirically sort out. It stems from my days of burning audio for older, OE car stereos because iPods hadn't come around yet :P I would like...

    Can’t get PM7220 to boot

    At least on mine you can switch between Apple // mode and Mac/Lisa mode, which will happily do 400k-1.4M :) You might need to read up on the documentation, as I think you need to wipe or swap microSD cards, as it's Either-Or, for the operating modes. If you tracked down a copy of Adaptec Toast...

    Can’t get PM7220 to boot

    Just curious here. What speed did you burn it at? This is anecdotal, and may very well not be universal, but I've had to burn my discs very slowly (1x or 4x at most) to get a copy that will be read on older CD-ROMs. Also, was it a garden-variety CD-R or a CD-RW? RWs tend to not read well on...

    Possibly a prototype Power Mac 4400

    I'm super fond of the CF adapter, myself :) theres just enough room for it under the drive chassis. Alternatively, you could do one that fits in an empty PCI panel and then just attaches with the ribbon cable. Go for a Cisco router CF card, as they have low writes on them and are generally very...

    Possibly a prototype Power Mac 4400

    Not your fault :) I've peddled my fair share of misinformation from other sources I considered data-driven. It happens. The problem with video media is annotations are ...hard :ROFLMAO: whereas articles can be edited and changes called out. I mean, honest mistakes are just that. I can do a...
