Upgrades
"If you have a Kaypro PC with 4.77 Mhz clock, you can buy one of two processor boards from Kaypro Corporation that offer faster clocks. These are the 8 Mhz 8088/V-20 board, part number 5238; and the 10 Mhz 8088/V20 board, part number 5962. Many PC owners already have one of these boards — they've been standard equipment for almost two years now. If there is a toggle switch on the back panel of your computer near the reset button, then you already have either an 8 or 10 Mhz machine." (Profiles June 1988)
