Back in the early 1980s, a good friend let me use his computer to type up my resume -- my first experience ever with a word processor. The machine was a Kaypro (pictured above) which ran an operating system called CP/M on a Z-80 CPU. With a whopping 64 kilobytes of RAM and two 5 1/4-inch floppy drives, its capabilities were somewhat limited, but it worked as long as you remembered to save your document frequently.
I found the picture today here. Unfortunately, I've lost track of my friend.
Chuck, If you're out there drop me a line.
