Just to let the cat out of the bag… The reason I tagged @SuperSVGA is because he has built his own RAM cards for the Portable and solved key problems too that nobody else ever has: https://68kmla.org/bb/threads/the-most-powerful-68000-only-mac.49969/#post-563312 His tricks include getting...

Watch me recap the 165c DC-DC board in my newest video here...

@ClassicHasClass I used Gemini to glean relevant info from your URL about the Apple Display Card 8•24 GC.... 1. The Hardware Under the Hood A CPU on a GPU: The 8•24 GC isn't just a dumb frame buffer. It features its own onboard RISC processor—an AMD Am29000 running at 30MHz (with 64K of SRAM...

I’ll tag @MacEffects and @SuperSVGA in case they might know about Mac Portable RAM Cards.

I’ve long wanted to obtain one of those cards to do my own testing. Alas, they are harder to find than a vintage Xceed grayscale kit (and I have one of those, so I know). But if I recall correctly, at lower bit depths, that Apple card beats out any other vintage NuBus card, including my Radius...

Have a link to that?

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...

@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...

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...

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...

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. 😄

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...

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...

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...

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...

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...

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.

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...

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!

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...
