Few people have heard of it, yet many consider John Blankenbaker's KENBAK-1 to be the first commercial personal computer.

Koss introduced these headphones over 40 years ago, and they remain affordable favorites to this day.

Oddball Micros: Zenith Unleashes the 2-Inch Floppy


The Zenith ZL-1 MiniSport was released in 1989. Its main claim to fame was a "revolutionary" 2-inch floppy format, which stored 720K. The machine also shipped with 1MB or RAM which could be configured so that the "top" 384K functioned as a battery-backed solid state "C:" drive.

Apart from that, the machine's capabilities were similar to the popular Toshiba T1000 series; monochrome LCD screen with CGA video output, 4.77/8MHz Intel 80C88 processor. No mice, no Windows, just good old MS-DOS 3.3 in ROM.

The oddball disk drive made this machine a hard sell, and Zenith cleared out their remaining units for under $300 in 1991. I couldn't resist the blow-out price, especially since the machine featured a program called FastLynx that could transfer files to a "real" PC, just in case I felt the urge to store data on "real" floppies. Incidentally, FastLynx could install itself on a remote machine via a serial cable -- sorta like a helpful virus. Those were the days.
