When I was ~10, my parents spent £129.99 (a lot of money for them at the time) to buy me an Acorn Electron (a cut down version of the BBC Micro).
One thing that was frustrating for me at the time is that I had no one to answer questions. For example, I was writing some 6502 assembly to do something simple (I don't remember what) and the book (either the user guide that came in the box, or the Acorn Electron Advanced User Guide) said I had to provide some value using two's complement. I had no idea what it was or how to find an answer. So I wrote a letter (yes, with a stamp, in the mail) to a Teletext page where these things were discussed, and a few days/weeks later they actually answered my question on one of the pages.
