Should probably be noted this isn’t actually running on a pregnancy test, it’s a pregnancy test plastic shell with a replacement CPU and display.

IIRC only the display is replaced, the cpu remains the same.

  The CPU was changed. https://twitter.com/Foone/status/1302453805057896448 https://twitter.com/Foone/status/1302453805057896448 "The existing CPU can't be reprogrammed and the existing LCD can only show 4 things, so I had to replace both to make any changes. And the current version doesn't even fit into the shell! (although I'm certain it will when complete)"

    Ahhh, I stand corrected :) Sometimes Foone's threads go on so long that twitter UI just gives up on linking them, or so it seems.

      There's a Twitter App for Firefox https://addons.mozilla.org/nn-NO/firefox/addon/nitter-redirect/ https://addons.mozilla.org/nn-NO/firefox/addon/nitter-redire... that makes it possible to view several 160 char messages at the same time. Computers are so fast these days it is amazing.

        Minor nit - Twitter messages are up to 280 characters now. https://blog.twitter.com/en_us/topics/product/2017/tweetingmadeeasier.html https://blog.twitter.com/en_us/topics/product/2017/tweetingm...

        The fact that you need to install a browser extension or use some other tool to view tweets in this manner is a big indicator that something is either wrong with Twitter for these kinds of posts or these kinds of posts are better served elsewhere. It’s akin to writing a novel on post-its.

        Someone -- it may have been OP actually -- has said that his ADHD makes it impossible for him to focus long enough to write and publish a blog post for things like this, but Twitter is low-commitment, low-attention enough that he can get it done. I really hate Twitter for this kind of content as well, but I'd rather have it there then not have it at all.

  Yes, its a Doom running on a 4MHz 64Byte ram 8 bit microcontroller .....
  - nabla9 6y ago
    Doom does not run on 64 bytes of RAM. Original system regs were 8 MB RAM. You can run it on 4 MB and can shave off some more but you need 16-bit bus ~MB's of RAM to run it.

      I believe that's if you're running it under Windows, I feel sure I was playing Doom on DOS with 4mb ram. Edit: yep, https://oldpcgaming.net/doom-1-review/ https://oldpcgaming.net/doom-1-review/
      - nabla9 6y ago
        Yes. I remember that too. I edited it to 4 mb just before you responded. The point is you can't run doom on hundreds of bytes or even several kilobytes or in 8 bit microcontroller.

        Indeed, I didn't need to nitpick

Was searching for exactly that and couldn't find an answer. That's what I would've guessed that such an expensive display won't be on a pregnancy test. Sad. Hats off to this great achievement, even though it's not really all original hardware.
