  • how much of the design is about making it usable today versus just seeing how far you can push the 6502. Either way, it's a fun project.

  • 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.

  • While not "portable" in the common modern sense, we also had:

    Apple IIc (https://en.wikipedia.org/wiki/Apple_IIc)

    and it's younger and final brother Apple IIc Plus (https://en.wikipedia.org/wiki/Apple_IIc_Plus)

  • 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.

    Browsing 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)

  • Love to see some aluminum frame parts introduced. Not cast aluminum parts—perhaps a machined aluminum deck and bezel. (There are of course places like PCBWay that will CNC metal parts for you.)

    It would give the laptop a great deal of structural support and act as a secure place to mount the hinges (for example). Also a convenient surface to perhaps integrate with the heat sinks to pull heat out of the enclosure.

  • The 6502 is so primitive that it runs on an Atari equipped with 128 bytes of RAM.

    Yes, 128 bytes. Used for code, data, video, and everything else.

    (But it can address 64 KB)

    It is so primitive that it is unable to multiply integers. If you want to multiply, you have to write your own algorithm.
