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?

crippleware

   1. Software that has some important functionality deliberately
   removed, so as to entice potential users to pay for a working
   version.

   2. (Cambridge) {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. removing a
   jumper).  A correspondant gave the following example:

   In 1982-5, a friend had a {Sharp} {scientific calculator}
   which was on the list of those permitted in exams.  No
   programmable calculators were allowed.

   A very similar, more expensive, programmable model had two
   extra keys for programming where the cheaper version just had
   blank metal.

   My friend took his calculator apart (as you would) and lo and
   behold, the rubber switches of the program keys were there on
   the circuit board.  So all he had to do was cut a hole in the
   face.  For exams he would pre-load the calculator with any
   useful routines, put a sticker with his name on it over the
   hole, and press the buttons through the sticker with a pen.
