This is so awesome.

A Casio FX-730P got me through secondary school. Sitting there programming during every lesson instead of paying attention.

I just ordered a Cardputer Adv on a similar interest. I saw the Cardputer Zero is sold out on Kickstarter! I miss my LG Phenom :(

Man, one of these was my fever dream as a kid.

I love this, but feedback to the author: the combination of a quirky font and quirky colours make this incredibly hard to read.

I really enjoy this format. Like reading a story from the authors life. Like you might read in an autobiography. I don’t think I write this way very often, but I enjoyed reading it. My takeaway is to write a bit like a journal more often.

Just reminded me of my favorite toy as a kid, the IR-7000 [1]. I convinced myself I was Ethan Hunt riding around on my bike with it in my pocket. Cool to see this working. [1] https://segaretro.org/IR_7000_Communicator

What a wonderfully hacky project. That's what's possible when hardware is not deliberately made unusable by planned obsolescence.

These are not calculators, but pocket computers. Different markets (one crashed, the other still exists) with different hardware.
