It was the first really popular home computer and by today&#8217;s standards it was ridiculously limited. A modern computer has about 4 Gigabyes of RAM or more, and often has a hard disc of 1 Terabyte. In contrast, the ZX81 had the tiny RAM working memory of 1K and no hard disk at all.<br \/>\nNow, a RAM of 1K is tiny, so small that the computer had to compile each line of code as you entered it. On a modern computer, you would enter all the statements of the code and then compile it using today&#8217;s enormous RAM. You only know that you have made a mistake in your syntax when you compile it.<br \/>\nOn the ZX81, if you made a syntax error in a statement, the computer told you as soon as you pressed the Enter key! And it told you very clearly with a big &#8222;SYNTAX ERROR&#8220; message.<br \/>\nLife is like that, too, you know. You always get immediate feedback, even if you don&#8217;t notice it at the time. When you really begin to notice the feedback that you get after each step, you&#8217;ll realize that those things that used to seem to be limits were actually not so limiting at all.<br \/>\nI loved that old computer. It ran a version of Microsoft Basic, probably the best Microsoft product that I ever used and certainly the most reliable \ud83d\ude09<br \/>\nIt didn&#8217;t seem limiting at all. On the contrary, we wrote whole games within that 1K and had such fun and creativity flow.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When I was about 12 years old, I started to program on a little computer called the ZX81, an amazing machine that had just been released.
