Buyer's Guide to Computer Keyboards

When purchasing a keyboard for your computer (either initially or as a replacement), there are a number of considerations which should be taken to ensure that it is compatible with the computer and appropriate for your purposes.

CONNECTORS: First, you will have to make sure the keyboard has the appropriate connector for your computer. Most modern computers have a small, round PS/2 keyboard port, but some mid/late-90s models have a larger round 5-pin DIN-style port. PS/2-DIN adapters are available. A USB keyboard can be used if a free USB port is present, but it might be helpful to keep a spare PS/2 keyboard to use if technical problems occur (USB keyboards may not function in DOS or early versions of Windows). More expensive wireless keyboards are also available, but will only work if your computer has the appropriate interface. Extending the cord length may be a better (and cheaper) option, as PS/2 keyboard extension cords can be purchased very inexpensively.
