My first computer was about 32 years ago, it was a Commodore VIC20, it had 4kb of RAM IIRC, the whole thing was housed in something resembling a very thick keyboard, there was no hard drive, if you wanted to run anything not stored in the RAM then it had to be loaded from a cassette tape (ask your parents what they are were)
Graphics were in square blocks about the width and height of a standard cursor divided 8x8 into 64 pixels.
I thought it was amazing!
