Input One, March’s program of the month, is a great example of the kind of simple and brute force programming of the 1980s. This was a time when computers had little memory and their users had to use simple BASIC programming to get things done. The alternative was to buy a cassette tape of programs that took minutes to load even short programs, assuming they loaded at all. For the rest of us, we either typed them in or wrote little programs like this.
At the one level, you can sum up most programs into three big groups: business, gaming, or educational. Most of my programs fit into one of these base categories. The standouts are generally the animation or demo programs that really have no distinct genre. Even those, however, I can lump into one of the big three without much effort. There are times when these categories get blurred and a program can fit into two or more categories. This month’s program is one of those.
Mixing things up a bit, I thought I’d start off the new year without a game program. Instead, January’s program is Computer Talk, or Comp. Talk for short. Comp. Talk is one of several educational programs I wrote for reasons I’m not entirely sure of. Perhaps it was just the thing to do back in then. Many computer books, especially those that taught programming, had a mix of program genres. Whatever the reason, I wrote Comp. Talk as a way for the ZX81 computer to introduce itself and show a bit of what it could do.
