It was forty years ago this fall, in 1977, that I bought my first computer. I had little experience with computers prior to that – a few weeks working after hours on an APL system at the U of T, mostly to play games against the machine, reading a few magazine articles on the coming ‘personal’ computer wave. Nothing seriously hands-on, experience-wise, and no programming skills either. But as soon as I saw one, I had to have it. And so I bought one.
Since then, I have not been a day without one, and generally had more than just one in my home. As many as six or seven at one time, back in the early 1980s, all different brands. But that was when I was writing about them, editing computer books and writing computer manuals.
My first computer was a TRS 80, Model 1. TRS stood for Tandy Radio Shack. It was a 16KB computer (yes: that’s 16,384 bytes of memory) In comparison, my current laptop has 8GB, or 8,388,608 kilobytes: 512 times the Model 1’s amount of RAM!
It was powered by a Zilog Z-80 eight-bit processor. My current machines all run 64-bit, multi-core processors. It had no USB ports, didn’t use a mouse, and had no audio card. Smartphones today are more versatile and more powerful. But not as much fun.
Before I bought it, I debated for a week or two whether to get the TRS or the competing Commodore PET, powered by the 6502 processor. It had similar limitations in memory and input devices, but came with a green and black screen integrated with the keyboard in one unit. But the TRS was sold at a nearby Radio Shack store within walking distance, and they also offered nighttime classes to teach the basics. The PET was only sold at stores downtown, so I bought the closer one.
I had to boot it and load programs from a cassette tape player. A year or so later, I upgraded to a 64KB RAM system and dual floppy (5.25″) drives. Each floppy could hold about 160KB of programs or data. It had a standalone B & W monitor that didn’t have any graphic capability, although canny programmers used the blocks in the ASCII character set to create pseudo-graphics (a bit like today’s Dwarf Fortress game displays, but only in B&W).
