    Radius Rocket & SCSI Booster Clones

    @ufkel If you have the README file which mentions a v1.1, it stands to reason you must also have that v1.1 software shown in your screenshot. If so, please provide the download link. Thank you!

    Making the ULTIMATE SCSI Drive by Loading Images From an SD Card!

    Wow. I've never seen that been done before. Bravo for trying something new. New mods are what make this hobby fun.

    BlueSCSI on Macintosh Portable

    Remove the HQX encoding but keep it as a SIT file? i suppose that would work and the file wouldn't get mangled when transfered across the internet, but if you cannot even decompress a SIT file (which may be true if you cannot remove HQX encoding), then that would be a problem because the file...

    Starting tech meetups in your own area

    Woz is smart, unlike the tech media who largely lambasts the Portable while so conveniently forgetting what Portables were like in the mid-to-late 80's and how much those portables sold for. Modern media mislabels it a "laptop" which is was not. And while it was much more competitive when...

    Oh, yes. Here's my story, Scott... Back in July 2012, some folks were having problems getting registered on the MLA, so I sent a PM to a certain moderator (at the time) who I won’t name because he’s well known there, still high up in the ranks, and started there probably about when I did...

    Display graphic FULL SCREEN on Mac SE?

    Just wanted to update this thread to say that I started using some of the apps proposed in this thread on a 128K Mac, starting out with testing on the 128K RAM edition of Mini vMac. @Mu0n , your app unfortunately seems to require more RAM so it didn't work with 128K, but the "Paint Flipper" app...

    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...

    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...
