    VRAM - more speed, or just more colors?

    Have a link to that?

    VRAM - more speed, or just more colors?

    Normally, adding more VRAM will enable higher resolutions and/or bit depths. But in my experience with vintage Macs, a switch to higher bit depths like from B&W to 8-bit (256 colors), or from 8-bit to 16 or 24, tends to reduce machine performance. The same is true for the switch to higher...

    Disassembled ROM sources for Macintosh 128K, 512K, and Plus

    @jonathanschilling Great work on that. Did you happen to take into consideration Steve Chamberlin's commented Mac Plus code found below? https://www.bigmessowires.com/rom-adapter/plus-rom-listing.asm (Everything he did is marked with "@sc".) He did that for his ROM-inator I kit to...

    MacSD inside a Mac Color Classic 'Mystic' - possible?

    Not sure if that question is being asked as a jab at MacSD or something else, but I can vouch for MacSD being a great product, which isn't saying anything bad against other products either. In fact, on many compact Macs, including my SE/30 with accelerator, I've found MacSD to be equal to or...

    Macintosh Mini - (yet another) Maclock conversion project

    The use of Sheepshaver indicates this is a PPC emulated machine, and that would explain the use of OS 8.1 in the opening post video. Not an issue at all, just something I noted. I’ve never been able to get Sheepshaver to work on my modern Macs, but I’m pretty sure it won’t boot into System 6...

    Restoration of three Macintosh II

    Glad to see someone appreciated that photo I put together for my SE/30 Color Kit video with the two Compact Macs sitting on top. I wanted to illustrate just how massive the Mac II really is. It’s almost laughable huge. 😄

    Color Classic Flyback Replacement from LC5xx

    So, it seems you tried the 84V 13" High Resolution mod but later switched to the 68.4V VGA mod, which would involve not only the change in the Horizontal Deflection Voltage (aka "B+") as shown below, but also changing the Sense Lines too (not shown below) in order to bump the resolution to VGA...

    PowerBook 165c Recapping List

    No reply came to my opening post after several days of waiting, so I proceeded to order the exact Yageo, Kyocera and Wurth caps I mentioned. They arrived today and I measured them as shown below because there are always differences from published specs on Mouser: YAGEO ESS106M063AE2EA PURPOSE...

    Maclock to Mac Plus Conversion kits

    Same kind of corner damage on my box too, which I kind of figured might happen even before I ordered because I know well how AliExpress shippers pack and ship — cheaply, not expertly. But I’m pleased to hear they continue to ship the real logo stickers because they make the device special. The...

    68kmla MIA

    Glad to see you here, Brett. You joined the MLA about 4 years before I did. I was an active participant there until I left in July 2021, which was the summer we created TinkerDifferent. I haven’t posted in the public forum over there since my departure. Even though both forums use XenForo...

    What did you cook today?

    Wow! Really? “Grill flavor” is the taste to die for! A small hint of that is what makes Burger King best McDonalds too. Here in Japan, there’s a delicacy called Unagi, which is roasted eel. If you’ve never had it before, it sounds terrible. And it actually is unless it’s grilled. Even my wife...

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    I've heard other people tell me they can see the FPS like that, but I've never been able to figure out how different their version was from mine, especially since we both downloaded from Macintosh Garden. It's really strange. And yes, I've tried all the various screen sizes too.

    PowerBook 165c & BlueSCSIv2 Drive Mounting Issue

    That would require me to disassemble the PowerBook again to access the SD card. What I did instead was put SCSI Probe into the Control Panels folder, open it, click Options, then tick these two checkboxes: Upon reboot, both drives mounted just fine. It seems to be a good solution to the...

    PowerBook 165c DISPLAY QUESTIONS

    For Mac lovers who needed a portable, I guess. But my solution to save money and maximize performance in those days was to just stick to desktops. Anyway, thank you very much for the excellent info because you answered my question perfectly!

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    I did an exhaustive amount of research into that, asking many, many people. It was a dead end. But since were on the topic of Doom, I am thinking maybe @MacOfAllTrades might know because of their amazing work on getting it to function on an SE/30 here...

    PowerBook 180c Display RECAPPING LIST

    First off, @3lectr1c has a nice overview of the stock electrolytic caps for the 180c display on his MacDAT web page here: https://www.macdat.net/repair/cap_reference/apple/powerbook/180c.html And "halkyardo" in the other forum has posted his solid tantalum recapping experience here...

    What did you cook today?

    Homemade buns are the best. The only downside is they come out taller than a regular burger bun at McDonald's, etc. But if you don't mind the extra bread, they're great and healthier too, in my opinion.

    PowerBook 165c DISPLAY QUESTIONS

    Thank you for the feedback. It certainly doesn’t take a minute or even close to that for the screen to “settle“ at cold boot. There is no “throbbing“ either, and the flicker you see in my video was simply my camera not being synced with the LCDs refresh rate. Later in the video, I better sync...

    PowerBook 165c & BlueSCSIv2 Drive Mounting Issue

    Perhaps @eric or you other BlueSCSIv2 PowerBook edition owners might know, but I'm curious why only one of my two drives (on the SD card) mounts when I power on the machine, despite having a good PRAM battery. I am then forced to use SCSI Probe to mount the second drive, as shown in my short...

    PowerBook 165c DISPLAY QUESTIONS

    This question is for you experts out there, and that includes @Ron's Computer Videos & @Mac84 & @techknight . Because the display is Passive Matrix, is ghosting normal, or is it showing only because the stock caps inside the display haven't been changed? You can more easily see what I mean in...
