    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    To the thread more generally: I've still not been able to get significant support with PowerPC elements of the future version. One person got in touch but unfortunately they answer one out of three questions and then go silent for multiple weeks. I've made so little progress I've not actually...

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    Evening @Opualuan Do you have a PowerPC upgrade? The current latest published version is available for download here : http://stuffandnonsense.elephantandchicken.co.uk/?p=2519 I'll try to remember to keep that version up to date.

    Another way to clean isopropyl alcohol used for cleaning resin 3D prints

    Throw ice in every now and then. Leave a bit of headroom for the volume of ice you need. Alternatively, run the one coil through a second larger diameter pipe and connect the outer pipe to a source of cold water like a tap (if you're unmetered you could theoretically just run the far end into a...

    Another way to clean isopropyl alcohol used for cleaning resin 3D prints

    Just to remind people, in many places around the world there are legal restrictions on distillation sadly. Just saying in case you order a still and the police come knocking. I realise this isn't vodka, but the legal restrictions might not overly care. Additionally, as already mentioned, the...

    BlueSCSI and System Switcher basic question

    You'll be fine. The main trap is that there is a little latch on the big many pin connector in the middle of the board. It is on the far side so you can't see it. With the CRT neck not far above it, you want to make sure you push that latch, and then rock the connector side to side rather than...

    Lombard / Pismo CD & DVD module drive replacement and 'Master' IDE Hack

    That's a shame - I used that site when picking an upgraded drive for my Pismo. I didn't worry about the bezel in the end, but got a lovely DVD / CD writer. I'll just check what it was for reference, it worked with not messing with master / slave or anything. Just plugged right in. Works with...

    BlueSCSI and System Switcher basic question

    The main thing is you need the long T15 drive as mentioned. Then with the 4 screws removed, the trick to opening it without a mac cracker is to put the SE face down on the bed (not near the edge), and using the flats of your hands, sharply but not too hard, bring them together like you're...

    Power supply interchangeability between different 68K Macintosh models?

    I got muddled - the 7300 has a different connector like the 8600 and 9600. I wrote 7300 instead of 7600, which is the same as the others in that group I believe, like you say! I've just tweaked that list to correct it. It means that the 7300 drops off the list because to my knowledge, it is a...

    Power supply interchangeability between different 68K Macintosh models?

    Yes, but I struggle with troubleshooting them to be honest. I'm not 100% comfortable working at mains voltages. Personally I find PSUs more of a problem than anything else.

    Power supply interchangeability between different 68K Macintosh models?

    There is a lot of PSU interchangeability between macs (and not limited to one side of the 68k/PPC change over), but it is important to note that the power rating tends to slowly increased with newer machines. Off the top of my head the following are can be grouped... IIcx, IIci, IIvx, IIvi...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Perhaps - we'll find out. There are a couple of enhancements in the Classic ROM, but it might be for nothing. Some of the Mac ROMs only offer the enhancements when booting specific machines - the Classic ROM is a series of patches on top of the base SE ROM - if those patches don't apply when...

    Axial caps NEVER need recapping?

    Only thing I'd say is if you are trying to save money or keep a machine as original as possible, invest in a cheap component tester. They work surprisingly well and with a little guidance you can do things like check every cap in a PSU and verify the condition. This can be a real money saver...

    Axial caps NEVER need recapping?

    Yeah, never say never. I've not noticed people saying axials never need replacing, it is certainly less frequent, but what I tend to say to people is that machines with SMD "tin can" electrolytics from between 1988 and 1992 are recap on sight. Everything else is recap based on condition - i.e...

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    Interesting - how have you connected into the edge connector? Or is that the problem? You can find the schematic for the 575 here : https://www.macdat.net/files/pdf/apple/schematics/apple/lc_575.pdf If you want to just get it running, most Macs will boot with only 5V, so you can probably...

    Hacking FinderHack: CMD-DEL for System 7.1

    I'm not sure that much effort is worth it for saving a couple of seconds, you're asking a lot of someone - you're potentially asking someone to patch the OS. Plus something probably already exists.

    Hacking FinderHack: CMD-DEL for System 7.1

    Yes sorry, that is what I was saying above, sorry I wasn't clear. You just need Finder 7.1.3 or later - I didn't realise that AppleScript could install it, that is a nice free upgrade. Despite what many applications say in their readme, a lot of software that says it needs System 7.5.0 minimum...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Well, that solves the mystery. Only thing I'd say is when I asked for a photo, I was looking for confirmation of what was absolutely in the board. Providing a photo of what you thought was in the board was perhaps counter productive and a little misleading. But... we all do things like that. In...

    Hacking FinderHack: CMD-DEL for System 7.1

    Ah well, I make more typos than most. Especially when fighting auto correct on my phone. Its worth checking around an error, before and after, when something like this flags up. Errors in code are notoriously cryptic on a good day, and just... well, wrong, other than the fact that there is an...

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    Also, if you are a toad. My most watched video by far is just a 30 second "I found a TOAD!" video of this cutie : Not saying it has that many views, but it has more than anything else I've uploaded. Note my channel is a sort of video notes I share with friends, family and people that might be...

    Universal System 7.1.2 68k Update Disk Set

    As mentioned elsewhere, for clarity on this thread - System 7 Pro is specifically System 7.1.1. The System 7.1.2 update can be applied to System 7 Pro, but can also be applied to System 7.1.0 and so 7.1.2 isn't itself specifically "Pro". Because you started from 7.1.0 JDW, you are running...
