    [SOLVED] HyperDrive Mac512 is a Sad Mac 0F0100

    After spending a whopping 8 hours in total on this mess, I finally found a solution. I finally found a FloppyEMU I use with my Apple IIc, flashed Mac firmware to it, then added many blank MFS 400K disk images for the purpose of making a backup. Using the HyperDrive Backup app, everything went...

    [SOLVED] HyperDrive Mac512 is a Sad Mac 0F0100

    Folks, if any of you happen to be owners of a GCC HyperDrive, I would appreciate hearing your thoughts. Mine is a 10MB drive mechanism installed in a Macintosh 512K with 64K Rev.B ROMs, and has an internal 400K floppy drive. I made 3 videos about my setup in the past so by watching those you...

    How to de-yellow the SPACEBAR

    Here's a photo of the metal hooks I mentioned in my opening post. The paint started to come off after having been dipped in the RetroBright liquid all day, showing the power of the deyellowing soup! Anyway, I simply taped those to the bottom of my Tupperware bin with masking tape, and then...

    BlueSCSI on Macintosh Portable

    Indeed, I have no lead acid battery at all to use, which is why I purchased the Battery Eliminator from @Androda . But as I have said in other threads, the Battery Eliminator has one important consideration. It acts as a never draining battery that has no charger (ac adapter) attached. That...

    Logic Board - Macintosh SE Reloaded

    Kai, is the MacEffects board a revision older than the matte black boards you kindly sent to me a long time ago? The reason I ask is because I never had a problem with RAM configurations on my matte black boards. As mentioned in the section of my video below, my matte black boards are...

    tinkering with compacts all winter?

    Wow! Those boards look fabulous! Did you have PCBWay or JLCPCB (whoever made them) solder all those tiny components on the bottom side of the boards so you won't need to deal with that?

    BlueSCSI v2: Sluggish Performance on SE/30

    I'm so sorry, Drake, I'm just too busy converting this thread into Braille right now. After that, sign language. Then, Swahili. We've gotta get the word out! ✌️ Oh yes, Klingon too is coming soon! https://www.translate.com/english-klingon

    BlueSCSI on Macintosh Portable

    Not being a BSv2 designer, I am ill equipped to comment about why that happens, but perhaps @Androda can share some thoughts when he has some time. The only thing I can share is my experience with my 2023.03a "forked" BSv2 (with PICO W). The resistor mod seems to have worked for me. Even so, I...

    BlueSCSI on Macintosh Portable

    "Fully functional" in terms of "data transfer" is key, and I know that is what you mean here. Even so, if you every decide to buy another "data" cable as a backup, it's a good idea. There are charging-only cables that screw up everything. I hate those and try to trash them when I find them...

    BlueSCSI v2: Sluggish Performance on SE/30

    Had I silently followed the guide and mentioned nothing in a post, it would not have gotten me benchmark scores from other people, nor would my investigations have assisted others. Indeed, my previous post makes this thread all worthwhile. It is an investigatory thread. That information we...

    BlueSCSI v2: Sluggish Performance on SE/30

    @eric , @This Does Not Compute , @speakers Thank you for your kind replies, and for the very helpful results. For the record, I am using the HD SC Setup (patched) 7.3.5 driver on all my virtual drives, which is the officially sanctioned driver in the vast majority of cases, as per this...

    BlueSCSI v2: Sluggish Performance on SE/30

    After several hours of failed attempts, I finally have zero fragmentation. Even on my Intel Mac, it was tough, but in the end, I found there is NO WAY IN HELL that an Apple Silicon Mac will achieve this. So people who don't have an Intel Mac are out of luck. Here's my log file content now...

    BlueSCSI v2: Sluggish Performance on SE/30

    Despite having disabled Spotlight in the Terminal, even after I freshly format the SD card as ExFAT, I still see it writes these hidden files: I don't know what's happening that causes my files to get fragmented. I write and write and write and write, check and check and check and check, and...

    BlueSCSI v2: Sluggish Performance on SE/30

    @robin-fo There actually was and still is fragmentation because after updating to Apple Silicon Macs, my SD card life has become a living hell. No matter how many times I format the SD card ExFAT and then write files one at a time, one or more of my 2GB files ends up saying "fragmented" in the...

    BlueSCSI v2: Sluggish Performance on SE/30

    @speakers Thank you for your kind feedback and willingness to test. MacBench 3.0 is brain dead when it comes to crashing, but it's the newest version we can run on an SE/30. It's also far better than SCSI Director Pro 4.0 to give you a complete idea of how faster your drive is. But I get...

    BlueSCSI v2: Sluggish Performance on SE/30

    Kai, thank you very much for your reply! I have two BlueSCSI v2's, both with PICO-W. Each have their own SD card, each card formatted with HD SC Setup 7.3.5 (patched). I have verified the "7.3.5" driver is correct using SCSI Director Pro 4.0. One card is a SanDisk Extreme 32GB V30 uSD, and...

    BlueSCSI v2: Sluggish Performance on SE/30

    SE/30 owners, if you have a BlueSCSI v2, could you please run MacBench 3.0 "All Disk Tests" and post your scores? (Please use only MacBench and only version 3.0.) I'm seeing seriously sluggish BSv2 performance in MacBench 3.0 on my SE/30 (with or without accelerators), despite the fact that...

    Radius Rocket & Radius Thunder 24/GT compatible?

    I acquired my Rocket from the original owner who at some point in the past had removed the CPU in order to repurpose it in another Mac. So before he shipped the card to me, he acquired another 68040 CPU which of course did not have a heat sink on it, and he sent that CPU to me along with the...
