crippleware n.
1. [common] Software that has some important functionality
deliberately removed, so as to entice potential users to pay for
a working version. 2. [Cambridge] Variety of guiltware that exhorts you to donate to some
charity (compare careware, nagware). 3. Hardware deliberately
crippled, which can be upgraded to a more expensive model by a
trivial change (e.g., cutting a jumper).
An excellent example of crippleware (sense 3) is Intel's 486SX
chip, which is a standard 486DX chip with the co-processor diked
out (in some early versions it was present but disabled). To
upgrade, you buy a complete 486DX chip with working
co-processor (its identity thinly veiled by a different pinout)
and plug it into the board's expansion socket. It then disables
the SX, which becomes a fancy power sink. Don't you love
Intel?
