    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...

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    But just to be clear, I am absolutely amazed how little interest there was because to me it is a really exciting awesome thing to discover you can do! To give an idea of the lack of enthusiasm... want to guess how many people followed the link to my blog post out of the first 1400 views of the...

    Hacking FinderHack: CMD-DEL for System 7.1

    Weird, but probably fine. I think it has decided you need at least 7.1.3, but doesn't realise that 7.1.4 meets the criteria. Hummmmm That isn't the usual AppleScript installer. What about in the Extensions folder, did it install "Scripting Additions"?

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    I appreciate the enthusiasm, but take care that not everyone is the same type of collector or person, as much as I'd like to see some testing done and people to enjoy using the software, it is up to people to use their computers as they want. Truth is I just want to get some testing done so I...

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    The chipset was designed to work at 40MHz, the only limiting parts are the exact speed of the RAM soldered on the board, the CPU grade, VRAM grade and the type of MC88916/88920 fitted. If you have an MC88920DW70 fitted like I anticipate you have, 40MHz is a fairly mild overclock (it is rated for...

    Hacking FinderHack: CMD-DEL for System 7.1

    That error looks like you don't have the normal scripting additions installed - they go in a folder in extensions. Yeah, I wouldn't install 1.0 or anything if newer versions exist. I'd go for a bit newer than that. I'd install version 1.1 which is what I'm using. It should include the Scripting...

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    You'd be suprised. There has been almost no interest. I've only been able to get two people to do any testing, and only one of them has a PPC card... after posting here, a friend posting on reddit, it being on my website, and on youtube. Plus I directly contacted everybody I could think of that...

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    It isn't publicly available yet, I've been struggling to get testers to finalise it.
