The new Apple USB-C power bricks for the M1 Max / Pro laptops are 28v @ 140w. This is more than enough to run a G4 cube (which is not using an ADC monitor). Older USB-C adapters may be sufficient in some circumstances but I don't believe they have sufficient wattage / headroom for spikes.
I’m happy you were able to make progress - frankly, the Cloney Clip has many barriers to entry and failure points. With the 3D printing, pogo pins, and finicky cabling its an accomplishment. There’s a simpler iteration I’m exploring but it’s more “one time use”.
I haven't had any timing issues with RGBtoHDMI, but to be fair I've only tested on the 128k, 512k, Compact Mac, and "dabbled" with the SE. It's just too bad it's not easier to buy the RGBtoHDMI premade or they would be a massive hit.
I have no clue if this is helpful to anyone here, but I made a backlight mod for the Weller WE 1010NA.
I have a few boards for sale ($10 + shipping) but the project itself is open source and designed so you can order them pre-assembled from JLCPCB. The goal of the project was primarily to show...
I've made a few small updates to the original ROM-inator project by Big Mess O' Wires. Anyone interested can find the details in my GitHub repo — if you enjoy this project please leave a star, it's the closest I can get internet karma 😅
Please remember, the original ROM-inator is deprecated and...
Do you have more information I can refer to? Could be interesting.
I believe the 512k is backward compatible with 256k; only the first half of the memory gets mapped. Admittedly, I don't know for certain.
Is there something particularly grievous about the project I've shared? Your responses sound very snarky!
The EasyEDA source files are in the repo. There are tools to convert the EasyEDA files to other formats (e.g., KiCad). Because I do not use other tools I cannot confirm the accuracy of...
The project was designed in EasyEDA. Thanks for your feedback!
edit: EasyEDA source JSON file is in the "gerbers" directory and the first paragraph of the repo's readme has a link to the open hardware source, which includes access to the schematic sources. (y)
I've released the schematics, gerbers, and PCB files for a VRAM version based on the Apple 820-0605-A 512kb VRAM (GitHub). If you appreciate this project I encourage you to star the GitHub repository and share it with friends.
