Watch my video from 3:13 to 4:08 for all the details on that component:

Those are large solder pads under the power switch, and to better reflow mine, I used a soldering iron just after heating the area with a hot air station. I used flux to better ensure good solder flow. Very well could be that even if you've desoldered before. Also note there is one extremely...

While I certainly appreciate the positive encouragement, I'll stick to filming YouTube videos in top quality 4K. That's what I do best. :-) I simply enjoy filming the 3D prints made at JLC from the STL-creating geniuses out there. Working on a new video now, in fact. Some of the 3D prints...

@frontein1 To supplement my previous post (you may wish to re-read that because I added edits to it throughout the day yesterday), I have even more info for you. @phipli offers his C SOURCE CODE here: https://github.com/Phipli/Soft-475-Overclock/blob/main/Extension%20MacBinary/INIT.c.bin It...

Whether a painted stock case or 3D printed, I took note of the bottom "lip" of the floppy slot having been perfectly filed down at an angle... @jmacz we need full resolution pics! :p That one thing being a 3D printable DRIVE BAY for any 3.5" drive, be that spinning platter type, MacSD...

Now that you mention the clear case, a bracket printed into 100% transparent resin would look better than Velcro. :-)

60ns Yes. See the 4th page of the attached PDF schematic of the LC575 motherboard. 475 Overclock Software by @phipli requires MEMCjr to do its magic. You can download the MEMCjr datasheets here...

To @Drake and whomever else might know... Does the resistor overclock mod increase the clock speed of the CPU and the FPU too? And does it boost the BUS SPEED? I'm just curious if the resistor mod transforms the LC520 board into an LC550 board, which of course means CPU, FPU and BUS Speed...

@wottle Thank you for replying, but I was afraid of that. So many brackets use that expansion port, but that doesn't work for a Mac SD, and my middle name is "PDSCARD" so I have the need to mount it in a bracket directly above the floppy drive. I could just hack off the back end of the stock...

Does the eery silence mean none of you know? 😨

I've got the v092 firmware flashed to my Universal ROM SIMM in my LC575 motherboard (Color Classic Mystic). Booting into System 7.1, I see I only have 32MB RAM now instead of 36MB, which is expected. I am using the Soft 475 Overclock by @phipli to overclock my 040 CPU, but I am not seeing any...

I'd like to thank @Willj for his kindness in providing me with the following link, which I can now provide to all of you: https://www.peconnectors.com/sockets-pga-cpu-and-memory/hws1788/ That price of $4.85 isn't too terribly bad, but that company is extremely frustrating when it comes to...

SE & SE/30 Drive Bracket Aficionados, I installed my MacSD (created by @YMK ) into my SE/30's stock metal bracket as shown below (my finger is touching it), but I hate those brackets because they cover the main wiring harness connector and make it a huge PITA to remove that connector! My Mac...

Thanks for the feedback, @dougg3 ! I wouldn't worry about that. I was actually rather disappointed this thread hadn't gotten more traction and largely was falling by the wayside. So this recent dialog about the programmer is a adding a nice "bump" to the thread. I suspect that one reason...

@dougg3 I'm going nuts! Just fired up my old Intel mid-2015 15" MacBook Pro running MacOS High Sierra and downloaded your v2.0.1 SIMM Programmer app. Sadly, when I launch the app and then switch on the ROMmate Programmer v2, the app won't recognize the programmer. 🤦‍♂️ Used Boot Camp to boot...

Had no time to try and flash the v091 or v092 ROMs until this evening, but sadly, my ROMmate v2 programmer simply is refusing to do the job! Is the SIMM Programmer app incompatible with macOS Sequoia? I tried using my standard cable multiple times to no avail. I tried multiple USB-A to USB-C...

This thread caught my eye today, and it raised one big question in my mind... How do you NeXT owners use the machines? For example, I can tell you how I use my vintage Macs (which are mostly 68K machines): Gaming, HyperCard, Photoshop (believe it or not, yes), Benchmarking...

After my 84V mod (640x480), the heat of the 18V 5W Zener used at DL22 caused me a lot of lost sleep. I just wasn't satisfied with the heat it put off. After some in-depth study, it seems the way these Zeners keep cool is to dump all their heat into the legs, which is why the two stock Zeners...

Or a small flathead screwdriver that you can use at each end of the chip to slowly and carefully wedge it out. Mixing the chips won't harm the board.

Congrats, @Mac84 ! I didn't watch your entire video, but I did catch your exuberation and "Holy Crap if F'n works!" :LOL: Glad to see it was just the cable because those solutions really are the best kind. No soldering, cleaning or hacking required in that case! Just curious though if...
