    Color Classic analog board trouble

    Thank you! Very interesting that your blue, 1W-rated replacement also burned. So by saying "4" you mean you have the equivalent of a 4W resistor in there now?

    Color Classic analog board trouble

    Wow! So it looks like things are working now. And all because of a tiny shaving of solder! But can you show me where in your photos RL62 is located? I Googled up other CC analog board photos but can't seem to find it inside the shielded cage. (And I don't have my CC open in front of me to...

    Color Classic analog board trouble

    I am quite curious about Soft-power having worked originally when you got your hands on that CC, but then after recapping, you said the machine powers on immediately by the mere flip of the switch on back (which should not happen). We know that soft-power is merely the grounding of pin-2 of...

    Color Classic analog board trouble

    I downloaded the attachment in the opening post, but I needed to change the extension from .txt to .html and then I could view it. Nice info! I spoke with Kay Koba, who is truly my Sensei about all things related to the CC, and he is unsure about the root cause. He is concerned about the...

    SE/30 RAM Banking QUESTION

    @Croissanting Seeing your photo upsets me greatly because no expensive sockets like that should break so easily! And these are expensive! So what I am forced to do is use both hands and press outward on the metal tabs of the socket while I carefully and slowing insert a SIMM and pull it into...

    SE/30 RAM Banking QUESTION

    It's a travesty, to be honest. Even if we argue that the sockets which broke in my case broke due to age and humidity, the fact remains that many vintage sockets withstand even longer spans of time, and all the humidity during those years, better than these "new" sockets do. These are RAM...

    Crucible for the SMC ROM SIMM

    The BMOW ROM-inator II gives users the option of pressing a keyboard key to choose either ROM Disk or RAM Disk (where the content of the ROM is loaded into RAM for the purpose of changing data, which cannot be done on the basic ROM Disk)... But I believe Kay's ROM is ROM Disk only. There...

    Crucible for the SMC ROM SIMM

    The only thing close to what you are asking is DiskDoubler, but I don't think that will work on this time 1.5MB image. You can test it with Mini vMac though and see.

    Crucible for the SMC ROM SIMM

    As mentioned in my previous post, you must create a 1.5MB disk image with *.img filename extension. You can leave your 1.5MB image to be blank, or you can put only apps on it, or you can put a System folder on it (only one SE/30-compatible System folder will fit into 1.5MB). It's entirely up...

    Crucible for the SMC ROM SIMM

    @OneGeekArmy & @Kay K.M.Mods Thank you for explaining. I understand now. I was simply confused by the earlier video which showed 3 images (System 6, System 7 & Blank) all being used with Crucible... It is pretty obviously that all 3 disk images show above wouldn't fit into a single 1.5MB...

    Crucible for the SMC ROM SIMM

    @OneGeekArmy I am not 100% clear on the complete procedure. Could you please confirm if the following are the exact, correct steps for people to follow in conjunction with the Crucible software? Create a boot disk *.img file that is no bigger than 1.5MB, and put it into a folder on the...

    SMC 4MB Memory Card, Bare PCB Kit

    Correct. The speed of your donor SIMM’s RAM chips determine the speed of your DIY SIMMs. 60 ns is fast enough for any Mac that is compatible with 30 pin SIMMs.

    Monitor Sad Shipping Story

    I take it you did not issue specific instructions to the seller regarding packing. I failed to do that long ago but soon learned that "people are stupid." I sometimes feel I am a complete idiot until I realize there are a huge number of people out there a lot dumber than I am, not because they...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Even if the IIfx had a fast SCSI card installed, I would guess the Mystic would be faster overall due to the faster CPU.

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    I look forward to your test result. And who knows... You just might be the first person to use a "Jackhammer" on a BlueSCSI! 😄

    SMC ROM SIMM Prototype

    My first home computer was the MacIntosh 128K in 1984. Through all these years, I have never owned a single Windows PC for home use. So even though I probably can buy a PC for my home use for only $100, it would cost me a lot more than that in my time to set it up directly. It’s probably easier...

    SMC ROM SIMM Prototype

    Maybe it's good to stay with the TLS866+, not only for the MacOS software, but also because it can program your ROM chips and just about anything else too, including the ROMs for a Mac SE and other programming projects like that? SOURCE: https://groups.google.com/g/sebhc/c/Hn0xDdiyryc

    SMC ROM SIMM Prototype

    If you buy the 12pc programmer kit using Kay's AliExpress link, it includes the PLCC32 adapter (no need to buy that one adapter separately in that case)... But what's the link to the MacOS software to control the programmer?

    SE/30 RAM Banking QUESTION

    Not sure where Kay sourced the ROM socket he installed in my SE/30 motherboard, but I purchased the RAM sockets from RS Components Japan and had them directly shipped to Kay. In the first batch, which was foolishly shipped in a mere bubble-wrap envelope, 4 of the sockets were chipped, but we...
