What was your first computer?
An Apple][ with 48 KB of RAM with a cassette recorder as mass storage.
Then came a diskette drive which Apple manual was written in 2 colors: black for questions and green for answers, unfortunately, after page 24, the green was definitely missing from the printing -- which gave me a great taste (and skills) to investigate about hardware functionalities
Looking backward, it is amazing what we were able to make and achieve with so few memory and display, comms, etc limitations ; may be my taste for the Linux command line comes from there - that also lead to a concern about programs always being able to run on older hardware without problems ; something that so called web developers (and many others in fact) should take in account when they develop new "code" on their 128 cores with 512 GB of RAM that can't run under a consumption of 50-100 MB RAM or even more and bloats so much that some can't work correctly if you don't have a recent computer…
Naturally, this lead to SBCs, oddly not so long ago, because I was waiting for such a SBC as the Raspberry Pi 4 with 8 GB RAM with the aim of being able to supply a very-cheap-but-not-that-weak computer to people that are missing the money needed to pay for a x86 - and it's not only these people that are interested in, but also those who do not need 64 cores with half a Tera of RAM because they have the most basic usage of a computer, such as reporters, that mainly have to read articles and thei e-mails, watch videos and TV and write, nothing much more than that.
RPI4 was quite a shock either visually speaking, you see many pictures, even of a RPI4 in a hand, you take a graduated ruler to imagine the thing, but you (well, I) do not realize how small it really is until you see unbox it - the second shock was the raw power it can deliver. When I think back about 6502 (reasonably speedy at… 1 MHz) or Z-80 or even MC68000, I was far from figuring correctly how powerful CPUs would be more than 40 years later and how much it would be interesting to have a GPIO onboard for people wanting to learn a bit of electronics and/or realize what they have in mind.
