    Radius Rocket V1.0 - Error #4614

    @max1zzz has extensive experience with that edition Rocket because he has cloned it... https://tinkerdifferent.com/threads/reverse-engineering-the-macintosh-iicx-logicboard.905/page-2#post-33828 My Rocket, however, differs from yours because mine is the ASIC version that looks the photo in my...

    68kmla MIA

    Tom Levens, who ran the MLA prior to Cory. Out of all the people I've encountered in this hobby, it's hard to believe YOU would have ever gotten a Warning Point, Scott! Wow. But yeah, when forum administration isn't so great, that sort of thing can happen to even the best of people, sadly.

    Portable Misc - Hinge clip fix, Earlier features, Super Static memory

    Listen to the official Apple mention at 8:36 here: And for the doubters, Logical Deduction that even Spock would appreciate also comes into play. 🖖 The Macintosh Portable housing is absolutely made of Polycarbonate, based on the fact those machines just don't yellow and the housing is...

    Portable Misc - Hinge clip fix, Earlier features, Super Static memory

    What specific part number of Gorilla epoxy did you use? And, have you tested how strong the bond is to polycarbonate? I used DCM to weld the broken hinge when I did my repair (which is a different part than what you repaired). But the key difference is that my break was clean without gaps...

    ATTinyRTC: RTC Replacement for SE/30

    Thank you for those excellent questions, @luRaichu ! I don't have a Mac Plus in which to test it, sadly. And when I investigated Plus compatibility, it seems that he didn't test that either because he too doesn't have a Plus. In particular, Phil says the following: It seems the original...

    ATTinyRTC: RTC Replacement for SE/30

    Many of you are already aware of Phil Greenland's Github project where he uses ATTiny85 to replace the RTC (Real Time Clock) on SE/30 motherboards. It's neat because it saves PRAM to onboard flash memory. If you don't care about the date/time (doesn't get saved to flash), then you can forgo...

    I broke and fixed Macintosh Portable (backlight). Attached backlight circuit schematic that I reverse engineered

    Fantastic info! Love your partial schematic too! And to think... This is your FIRST POST here on TinkerDifferent! I'd like to offer you a very big WELCOME ABOARD!

    Portable CCFL Backlight Replacement with Off-the-shelf LED Strip Driver

    Noise suppression of ceramic caps is sometimes done by drilling holes in the board around the cap so the PCB won't act as a speaker cone, although I consider that a bit extreme. However, many manufacturers probably do that because noise surpassed ceramics are crazy in comparison to the regular...

    Portable CCFL Backlight Replacement with Off-the-shelf LED Strip Driver

    @David Cook Are you 100% certain its the coil and not the cheap ceramic caps? The expand and contract in some circuits, and like a loudspeaker, use the PCB to increase the audibility of their vibrations. Coils do whine though, so it very well could be the coil. Finding a solution to the...

    Portable CCFL Backlight Replacement with Off-the-shelf LED Strip Driver

    @David Cook You're like Scotty -- a real "miracle worker." I'm floored by the excellent detailed info you provided. You, sir, are to be highly commended for that ground-breaking work! I only gave your post a single read-through so I may have missed other negatives, but the only two...

    Logic Board - Macintosh SE Reloaded

    It’s actually pretty critical because I have accidentally reversed the cable I was inserting on the internal SCSI connector on my SE/30 more than once in the past. I try to be extremely careful about that now, but since it’s happened more than once before, and since I am getting older and feel...

    Radius Rocket & SCSI Booster Clones

    Good news. I was able to contact Petar Puskarich several months ago and confirmed he had the manual and software. Things fell by the wayside, and I only recently revisited that conversation with him. He very kindly took action and uploaded the SCSI Booster Driver to Macintosh Garden as DL#9...

    Logic Board - Macintosh SE Reloaded

    @Kris92 @Kai Robinson It would be greatly appreciated if one of you could please post photos or drawings of the precise location on the SE Reloaded motherboard and the exact pins that need to be either cut or jumpered, including the place where the jumper wire needs to be soldered to, taking...

    Macintosh Mini - Maclock conversion project

    @wells Have you put your STL files through the JLC3DP website to see if the size is large enough for them to do a PLA print? They have some pretty silly minimum size requirements that can be frustrating. If they refuse to print your files in PLA, they may allow it in Nylon. So I suggest...

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

    I can't speak to the "if at all" part above, but if an arbitrary rule of one decade is to be put in place, that would mean roughly Halloween 2034 (10 years and a couple days after Zane's last post in this thread). And since I have no means to do the work myself, and due to the complexity of...

    InventoryDifferent - Managing your vintage device collection

    Hey, @wottle. Fantastic work. Just wanted to post here to say that I found an price error on your Mac Portable page here just now... https://thearchive.inventorydifferent.com/journeys/apple-laptops Specifically, the Portable NEVER sold for $7,300. That $7300 amount has been spread...

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

    Technically, there is a legal issue (albeit, mostly in the minds of wannabe lawyers in online forums) with even recreating Zane's ROM, which is why the people who did that work tried desperately to contain Zane about it, and I volunteered to try to reach Zane on their behalf too. I have tried...

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

    No. I'd say it is unlikely this particular project will continue at this point, unless a brilliant member of our community tries to build on Zane Kamenski's incredible work by attempting to recreate it and partner with MacEffects or another vendor who can manufacture it for the masses...
