- Micro-computer based 6000 Series keyboards from Maxi-Switch represent an important advancement in keyboard technology. This new design concept uses microcomputer power to greatly enhance keyboard performance, while adding features and functions not possible with conventional designs. The microcomputer series uses either the new Maxi-Switch 6000 Series low cost mechanical key switches, or 2900 Series modular reed switches. The 6000 Series redundant mechanical contact design minimizes bounce and susceptibility to switch tease while providing long contact life. Reliability is not sacrificed to achieve low cost. 2900 Series reed switches provide added reliability with rated life of over 100 million operations, and sealed contacts to protect against hostile environments. Maxi's microcomputer-based keyboards feature six important design advantages: 1) Variable debounce, provides a fool-proof software debounce that insures against multiple character output. 2) Electronic hysteresis, prevents multiple character generation when the operator "teases" the switch by making small movements of the keyswitch plunger. 3) Design flexibility, is provided with a number of user-selected options which are chosen by the simple addition of diodes to the circuit board. 4) Smart keyboard design. Maxi-Switch keyboards can accomplish tasks not possible with conventional keyboard encoding techniques. 5) Modular software, allows Maxi-Switch to accommodate custom requirements without extensive or costly changes to the basic software. 6) Simple design. Most Maxi-Switch custom microprocessor keyboards require only two integrated circuit chips, for important cost savings and added reliability.
- The majority of switches bear a "Maxi" logo on the base. The decision of SMK to place the logos there means that there is no way to positively identify whether any particular switch is an SMK, Maxi-Switch or NEC product, although the choice of colors is a clue: a blue base (and thus retention clips) tends to suggest Maxi-Switch (although black bases were also used), while an all-black shell and blue plunger implies NEC. Heavier switches used for space bars and occasionally other keys have a pale blue stem. Switches intended for wider keys tend to have a beige body and brown plunger as with SMK switches. Switches intended for long, large and wide keys can have either a beige or a brown top — this follows on directly from the SMK practice, where these keys were denoted by Apple as "low friction".
- Despite being the first model to be released commercially, the original system was branded as the Kaypro II (at a time when one of the most popular microcomputers was the Apple II). The Kaypro II was designed to be portable like the Osborne, contained in a single enclosure with a handle for carrying. Set in an aluminum case, with a keyboard that snapped onto the front, covering the 9" CRT display and drives, it weighed 29 pounds (13 kg) and was equipped with a Zilog Z80 microprocessor, 64 kilobytes of RAM, and two 5¼-inch double-density single-sided floppy disk drives. It sold for about $1,795 (equivalent to $5,000 USD in 2021).
- Kaypro Corporation was an American home and personal computer manufacturer based out of San Diego, CA in the 1980s. The company was founded by Andrew Kay of Non-Linear Systems (NLS), to compete with the popular Osborne 1 portable microcomputer. Kaypro produced a line of rugged, "luggable" CP/M-based computers sold with an extensive software bundle which supplanted its competitors and quickly became one of the top-selling personal computer lines of the early 1980s.
- The Maxi-Switch Co. was an American keyboard technology manufacturer; in 1990, parent company EECO sold Maxi Switch to Silitek; a division of Lite-On.
