    "475 Overclock" control strip on Color Classic Mystic - problems and solutions

    Wait… Has SiliconInsider (Dr. Antoine Bercovici) changed his business name to Jurassic Computing? Because those are his products, and yet I’ve never heard of Jurassic Computing. if indeed, those are being sold by SiliconInsider, then they will work fine. And I must say, I’m a fan of his gold...

    "475 Overclock" control strip on Color Classic Mystic - problems and solutions

    I’m tagging @phipli because he might have some ideas. I myself and am very surprised to hear that you would need to use WISH I WERE on an LC575 motherboard to let 475 OC know it’s a 575! That’s just plain weird! There’s no harm in using the software like that though. But in answer to your...

    SMC ROM SIMM Prototype

    It wasn’t my intention to force you out of this thread. But I would encourage you to start a new thread so that discussions about your particular situation and programmer and ROM SIMM can be discussed at greater length.

    SMC ROM SIMM Prototype

    Friends, I humbly wish to clarify, without any offense to anyone, that this thread is entitled "SMC ROM SIMM Prototype". It is therefore tied to Kay Koba's products found at his website here: https://en.infinityproducts.co.jp/product-page/smc-rom-simm-card...

    Differences in grayscale options for the SE/30

    That's the one thing which always irks me about my Xceed cards. (I have the MacroColor 30HR & Color 30HR.) When I compare with stock video, stock video is brighter, without being blown out or overly bright (where the black surround starts to brighten). So if the 30video can yield 256 grays at...

    Synchr030/S 256MB SDRAM Accelerator for the SE/30

    I'm truly thrilled to hear that ResEdit hack on the Finder worked! And I apologize I myself haven't found time to test it yet. Fabulous to see 256MB fully accessible under System 6.0.8 (hacked Finder) with full acceleration too! And just so everyone reading this is aware, Optima did have...

    Synchr030/S 256MB SDRAM Accelerator for the SE/30

    The Optima page on Macintosh Garden has only a single download. No PDF manual is offered, sadly. But I downloaded and Unstuffed the file and found there are two versions, each with their own README files: The README for Optima 32 v2.0 says this... No mention of 6.0.8 :( The README for...

    Color Classic analog board connector is *very* sensitive

    Great to hear you solved the problem, but which tabs are those? The photo is a bit blurry. Maybe a shot of the full board would help put it in perspective. But regardless, I agree that a PROPER GROUND is critically important for those machines, and it's easy to accidentally miss that if it's...

    128k MacSnap Reloaded video

    I'd like to mention that I watched the video in its entirety (as all good videos should be watched), and it was a learning experience because I never knew anyone had done a MacSnap SCSI Reloaded. Look forward to hearing if ROM-inator Resurrections by @Kay K.M.Mods will work with the MacSnap...

    Synchr030/S 256MB SDRAM Accelerator for the SE/30

    The Synchr030/S documentation mentions a non-stock ROM as being very important, and in my video I stated it as being pretty much a requirement... "Required"? Really? Well yes, and for more reasons than just to become 32-bit clean. Because unless you want to sit through RAM checking for...

    Radius Full Page Display for Macintosh 512ke/Plus - Cloning project possibilities?

    I read through this entire thread today. Curious what the use cases are for the card WITHOUT the full page CRT. Because those are extremely rare beasts that I don't often see. And if the intent is to use a modern LCD, is there any meaning to clone the card? I also wonder WHY there aren't so...

    Synchr030/S 256MB SDRAM Accelerator for the SE/30

    I never tested Optima, so I have no idea. I searched the Synchr030/S documentation, but there is no mention of even System 6 or 24-bit addressing. I searched through past emails between myself and YMK (because there are so many), and I couldn't find "Optima" as a keyword. I then searched for...

    Texas Instruments discontinuing a lot of IC's

    That's component U4D on the Mac SE motherboard. I've been using the SN75150P on my BOM and Mouser Cart, and currently it's not EOL'd by Mouser yet. The TI product page also shows it as "Active."

    Texas Instruments discontinuing a lot of IC's

    Very interesting. I merely read the opening post where Kai said "any Reloaded boards" and just assumed that word "any" included his SE Reloaded board too. But per your request, after searching my BOM like mad, I do not see any reference to UC12 and UB12 or the SN75175 part number. So it would...

    Texas Instruments discontinuing a lot of IC's

    Thanks for the heads-up, @Kai Robinson . I made an announcement on my YouTube channel via Community Post just now, linking back to this thread. Those of you interested in browsing the parts list for Kai's SE Reloaded build, note that my BOM is here...

    What capacitors for 1.44MB floppy recap?

    Interestingly, I am not able to see your signature when viewing this page in Safari on my iPhone 15 Pro Max, as you can see from this iPhone screenshot... But I am now using Safari on my 5K iMac, running macOS Monterey, and I can see your signature now. I consider that to be a forum...

    Uneven color tone on Color Classic's screen.

    Yes, screen adjustment every time you switch resolutions would fast become painful. But I do see merit in having the stock resolution because everything becomes a bit easier to see. VGA makes everything shrink down pretty small.

    Uneven color tone on Color Classic's screen.

    What I show below is not irreversible. I would never reverse it, but I am mulling a change to the high voltage VGA mod so I can test the stock CC motherboard and LC520 motherboard. VGA mod for the Macintosh Color Classic (640x480) & Doping Mac
