The first computer I could really call my own was an Amstrad PCW9512. It was a word processor from 1985 that ran an operating system called CP/M. It booted from a disk as it had no internal hard drive.
It had a daisy-wheel printer that was extremely loud, as it was essentially an electric typewriter.
I learned BASIC on the Amstrad and used it to program my first text-based games.
The first useful BASIC program I wrote on the PCW was an address book. It wasn’t advanced enough to read data from a file, so it was a mess of GOTO statements that made for very basic name lookup. I was an absolute beginner.
I had a program named Dr Logo which could draw lines on the screen. It was possible to use loops to generate multiple lines and create shapes, like a digital spirograph.
I don’t have the PCW9512 anymore, but I do have a PCW8526 that still works perfectly.
