Qubie wants $199 for their keyboard. I don't know about the Qubie, but the Key Tronic unit (called the KB5150, since 5150 is the official IBM product number for the PC) also has some internal differences. The space bar lacks the stubborn resistance of the IBM's space bar. Also, the KB5150 has a different tactile feel, since it uses much lighter springs under the key cap, lowering the key resistance to 1.5 ounces (vs. 3 ounces for the IBM keyboard). The KB5150 doesn't click like the IBM PC keyboard. And the KB5150 uses a positive force tactile feel which maintains a constant resistance until the moment of contact (the IBM keyboard uses breakover tactile feel, in which the pressure builds up as the key is depressed, drops at the operation-threshold point, and then decreases at the end). The word is a skilled touch typist can pick up a few extra strokes by using the KB5150 instead of the IBM keyboard. Now if we can just get IBM to sell us a PC without their keyboard as part of the package... David Bryant Bell Labs Columbus, OH (614) 860-4516 (cbosg!djb)
