Very interesting project. It'd be nice to see video of it in action and what use cases the author had in mind. A pic in a different post shows the 48k ram chip, and not far away is an SD card of 1 gigabyte - that's a dramatic contrast. The storage can hold the contents of ram 21,845 times over. If an 8GB laptop today had the equivalent storage, it would be a disk of 174TB.
replyBrowsing by tag 'lt6502b' gives other posts that have pictures of the motherboard. https://www.maddox.pro/?cat=65 (update: the codeberg link has all the relevant pics)

The 6502 can't actually address more than that. The flash controller built into modern SD cards are also going to be significantly more powerful than the 6502. And I'm surprised you can even buy SD cards that small still!

That's a CompactFlash card. You often see them used in places where an IDE drive would have been.

What an interesting layout for a mobile site. It had the archive and a bunch of other stuff before the post. I thought OP linked something wrong.

Well, there was the Commodore SX 64. Not exactly lap sized but portable for sure.

A 6502 is capable of most actual workloads people have, whose profiles actually haven’t changed much. Almost all of our compute goes to GUI and rendering stacks that decorate our actual work.

Those people you speak of, how big are their numbers all in all you think? And is that a subgroup of a subgroup?
replyBecause most people I know certainly have different workloads and need their rendering as part of the work, not to decorate it nicely.
But for keeping a distraction free digital diary, it might be a nice device.
