The Kansas City standard

During episode #66 of This Week in Tech, host Leo Laporte reminded his fellow pundits that August 2006 marked the 25th anniversary of the IBM PC. It cost $1565—a fairly inexpensive computer in those days—but Leo noted that’s because it didn’t come with a hard drive, only a cassette port. John C. Dvorak immediately asked, “Does anyone remember if that used the Kansas City standard?”

My reaction was the same as Leo’s: Kansas City standard? Is that a joke? I grew up in K.C. and have lived there most of my life, and yet I’d never heard of such a thing.

This thirty year-old standard was actually fairly revolutionary. According to Wikipedia, it was one of the first standards to allow consumer-quality audio cassettes to store computer data. It was thus a catalyst in the rise of the personal computer, offering home users inexpensive data storage at a time when floppy disk drives cost around $1000.

An example comes from personal experience. I recall my dad’s old TI-99/4A having a cassette port to which he had hooked up an even older portable tape recorder. I’d use it to save my little BASIC programs and whatnot. I could turn off the computer then come back the next day, playback the tape, and pick up where I left off…hopefully. (As Leo says, those cheap tapes weren’t particularly reliable.)

Despite reliability issues, the Kansas City standard remained influential. It even spawned a completely new type of computer data storage: vinyl records! That’s right; old-fashioned 33â…“ RPM records were once used for recording high-tech digital data—formatted according to the Kansas City standard, of course.

And all this time I thought my home town was known only for its barbecue and jazz…
