    BlueSCSI v2: Sluggish Performance on SE/30

    I've not had time lately to fiddle, but I believe I tried that before and found hidden files were still being copied. What I can say is my experience on Apple Silicon is totally different than when using an Intel Mac. Basically, I cannot create a usable SD card on Apple Silicon. I am forced...

    BlueSCSI v2: Sluggish Performance on SE/30

    A “fix” for what, specifically?

    Disk Jockey v3 for macOS is out!

    @OneGeekArmy I for one am thankful for that "bright-eyed teenager" inside you. Every release is incredible. Just when you think Disk Jockey can't get any better, it does! Bravo!

    68k Mini vMac booting SCSI Device images

    I'm overjoyed at the changes, @eric. I confirmed just now that they all work great under macOS Monterey 12.7.5 on my 5K INTEL iMac from 2015. I downloaded all 3 Mac apps. Each boot my *.dsk images, and they boot my BlueSCSI drive images too, which is really the big appeal of your Mini vMac...

    68k Mini vMac booting SCSI Device images

    Could you please provide a link to that exact version? I'm eager to give that a test. I am using a late 2015 5K Intel iMac running Monterey right now.

    68k Mini vMac booting SCSI Device images

    It's been about two months, and I never received a reply to my previous post about the Sonoma requirement. Surely there MUST be a way to make it "Monterey or higher" compatible? I only have one Mac that can run Sonoma, and I use it less frequently than all my other Macs. While it is true...

    *Battery Gore Thread* NSFMacs

    But it didn't leak, right? I've not seen the Rayovac batteries spill their guts all over the place like the Maxell's so often do in SEs or SE/30s.

    BlueSCSI on Macintosh Portable

    Well, because you have a Fluke, I doubt Auto-Range had anything to do with it. Perhaps @Androda might have some good speculation, but I myself really have no idea why the mere presence of that meter (measuring only voltage, no less) would trigger one Sad Mac after another. Very odd indeed. As...

    BlueSCSI on Macintosh Portable

    @Paolo B So it would seem you have your meter set properly to measure Volts (not Amps), and the fact you could read 5V indicates you have the RED probe inserted into the proper jack in your meter to measure Volts (not Amps). So I am rather bewildered by why your meter, measuring only volts...

    Logic Board - Macintosh SE Reloaded

    @JdM74 , I will read and respond to PMs tomorrow because it's but a long and tiring day. But before I go to bed, I just want to say... SE Schematics (Apple and Bomarc) are downloadable here: https://macintoshgarden.org/apps/macintosh-se-schematics-repair The section showing J16 (RAM size...

    Logic Board - Macintosh SE Reloaded

    You are talking about J16, which looks like this on my matte black board: I never had a problem with it because I didn't use a jumper on it, and that's because I use 4MB of RAM, which doesn't require any jumper. I never tested lower RAM configurations because those configs didn't make any...

    BlueSCSI on Macintosh Portable

    If by "chunky" you means something like this... ...well, those will work too! They are normal silicon diodes like a 1N4004, but they are chunky boys because they handle 6 Amps! For long term use, their size may be a bother, but such diodes will work for testing purposes just fine, if you...

    Logic Board - Macintosh SE Reloaded

    I could have sworn I posted info about "Apple" logic board revisions and the associated ROM / IWM / SWIM chips somewhere in this forum, but none of my searches today found it. So I decided to post that info below in order to share it with @JdM74 and others. Apple Macintosh SE LOGIC BOARD...

    BlueSCSI on Macintosh Portable

    Not sure what a "PSU grade" diode is, so if you know the part number (often printed on the diode body), that would help identify what you have. I believe that any diode other than a Zener and other than a 1N4148 (which don't come in 1A varieties) should suffice for a basic test. Silicon diodes...

    BlueSCSI on Macintosh Portable

    I confirmed that the "always powered" solution proposed by @Androda works. No more freezes upon wake from sleep if WIFI was active when the machine went to Sleep, but I am not using it at the moment because it requires a male jumper pin to be inserted into one of the holes in the PDS connector...

    [SOLVED] HyperDrive Mac512 is a Sad Mac 0F0100

    One last thing. When you are finished using your HyperDrive Mac, it's highly likely you will move the machine. Before moving it, PARK THE HEADS. Sounds odd in 2024, but remember this hard drive is from the mid-1980's when heads were left having precariously over the disk platters UNLESS you...

    [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...
