@wells Have you put your STL files through the JLC3DP website to see if the size is large enough for them to do a PLA print? They have some pretty silly minimum size requirements that can be frustrating. If they refuse to print your files in PLA, they may allow it in Nylon. So I suggest...

I can't speak to the "if at all" part above, but if an arbitrary rule of one decade is to be put in place, that would mean roughly Halloween 2034 (10 years and a couple days after Zane's last post in this thread). And since I have no means to do the work myself, and due to the complexity of...

Sorry for the bother, but I just noticed your IIcx page says IIci on the Mac photo, so I fixed that for you here (same photo, just with cx instead of ci)...

Hey, @wottle. Fantastic work. Just wanted to post here to say that I found an price error on your Mac Portable page here just now... https://thearchive.inventorydifferent.com/journeys/apple-laptops Specifically, the Portable NEVER sold for $7,300. That $7300 amount has been spread...

Technically, there is a legal issue (albeit, mostly in the minds of wannabe lawyers in online forums) with even recreating Zane's ROM, which is why the people who did that work tried desperately to contain Zane about it, and I volunteered to try to reach Zane on their behalf too. I have tried...

No. I'd say it is unlikely this particular project will continue at this point, unless a brilliant member of our community tries to build on Zane Kamenski's incredible work by attempting to recreate it and partner with MacEffects or another vendor who can manufacture it for the masses...

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...
